After the 2020 United States presidential election, the campaign for incumbent President Donald Trump and others filed 62 lawsuits contesting election processes, vote counting, and the vote certification process in 9 states (including Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin) and the District of Columbia.Multiple sources:

Nearly all the suits were dismissed or dropped for lack of evidence or lack of standing, including 30 lawsuits that were dismissed by the judge after a hearing on the merits. Among the judges who dismissed the lawsuits were some appointed by Trump himself. Judges, lawyers, and other observers described the suits as "frivolous"Multiple sources: and "without merit".Multiple sources: In one instance, the Trump campaign and other groups seeking his reelection collectively lost multiple cases in six states on a single day. Only one ruling was initially in Trump's favor: the timing within which first-time Pennsylvania voters must provide proper identification if they wanted to "cure" their ballots. This ruling affected very few votes, and it was later overturned by the Pennsylvania Supreme Court.

Trump, his attorneys, and his supporters falselyMultiple sources: asserted widespread election fraud in public statements, but made few such assertions in court.Multiple sources: Every state except Wisconsin met the December 8 statutory "safe harbor" deadline to resolve disputes and certify voting results. The Trump legal team had said it would not consider this election certification deadline as the expiration date for its litigation of the election results. Three days after it was filed by Texas attorney general Ken Paxton, the U.S. Supreme Court on December 11 declined to hear a case supported by Trump and his Republican allies asking for electoral votes in four states to be rejected.

One suit, Michigan Welfare Rights Org. et al. v. Donald J. Trump et al., was brought by black voter groups in Michigan against Trump and his 2020 presidential campaign. Dominion Voting Systems brought defamation lawsuits against former Trump campaign lawyers Sidney Powell and Rudy Giuliani, each for $1.3 billion. Smartmatic brought a defamation lawsuit against Fox Corporation and its anchors Lou Dobbs, Maria Bartiromo, and Jeanine Pirro as well as Giuliani and Powell for $2.7 billion. In the aftermath of the January 6, 2021, attack on the Capitol, several civil suits were filed against Trump, sometimes in combination with other defendants. The plaintiffs include members of Congress, United States Capitol Police officers, and District of Columbia Metropolitan Police officers.

Two criminal cases were also filed, The State of Georgia v. Donald J. Trump, et al., a racketeering case against Trump and 18 other defendants, and United States v. Donald J. Trump, an election obstruction case in the District of Columbia. Both cases were dropped after Trump's election victory in November 2024, because of the impossibility of charging and trying a sitting president.

Background Both before and after the election, the campaign for incumbent president Donald Trump filed a number of lawsuits contesting election processes, vote counting, and the vote certification process in multiple states, including Arizona, Georgia, Michigan, Nevada, Pennsylvania, Texas, and Wisconsin. Many cases were quickly dismissed, and lawyers and other observers noted that the lawsuits are not likely to have an effect on the outcome of the election. Trump, his supporters, and his attorneys asserted widespread election fraud in public statements.

The Trump campaign suffered several setbacks on November 13, 2020. The Department of Homeland Security released a statement saying that the election was the "most secure in American history" and that there was no evidence any voting systems malfunctioned. Sixteen federal prosecutors assigned to monitor the election sent a letter to Attorney General William Barr saying there was no evidence of widespread irregularities. A law firm hired by the campaign in Pennsylvania quit amidst concerns they were being used to undermine the electoral process. The campaign dropped its "Sharpiegate" lawsuit in Arizona. A judge in Wayne County, Michigan, refused to halt the vote count or certification of the winner. In Pennsylvania, judges refused to block 8,927 mail-in votes in Montgomery and Philadelphia counties.

Four lawsuits orchestrated by conservative lawyer James Bopp in Georgia, Wisconsin, Michigan, and Pennsylvania were dropped on November 16 after a federal appellate court said voters could not bring some constitutional claims. Sidney Powell was dropped as a lawyer for the Trump campaign on November 22, and was operating independently on November 23.

By November 27, 2020, more than thirty of the legal challenges filed since Election Day had failed; by December 14, 2020, over fifty lawsuits had been dismissed.

Federal judges in Georgia and Michigan rejected last-ditch efforts by pro-Trump lawyer Sidney Powell to overturn the election results on December 7, 2020. United States District Court for the Eastern District of Michigan Judge Linda Parker wrote, "[T]his lawsuit seems to be less about achieving the relief Plaintiffs seek—as much of that relief is beyond the power of this Court—and more about the impact of their allegations on People's faith in the democratic process and their trust in our government." In the United States District Court for the Northern District of Georgia, Judge Timothy Batten wrote, "They want this court to substitute its judgment for two-and-a-half million voters who voted for Joe Biden... And this I am unwilling to do."

Judges who were nominated by Trump also dismissed the claims and reliefs made by the Trump campaign in the courtrooms.

Voting machine companies Dominion Voting Systems and Smartmatic threatened legal action, claiming that they were defamed by lawyers for Trump and right-wing media companies Fox, Newsmax, and OAN, who propounded conspiracy theories about the election technology companies. On December 18, 2020, lawyers for the Trump campaign told employees to preserve all documents related to Sidney Powell and the Dominion Voting Systems in relation to the suits. Dominion sued Fox News for $1.6 billion, and in February 2023 released subpoenaed internal Fox News communications that showed several prominent network hosts and senior executives—including chairman Rupert Murdoch and CEO Suzanne Scott—discussing their knowledge that the election fraud allegations they were reporting were false. The communications showed the network was concerned that not reporting the falsehoods would alienate viewers and cause them to switch to rival conservative networks, impacting corporate profitability.

Legal analysis and reactions Loyola Law School professor Justin Levitt said "[t]here's literally nothing that I've seen yet with the meaningful potential to affect the final result". Ohio State University election law professor Ned Foley noted "[y]ou have to have a legal claim, and you have to have evidence to back it up. And that's just not there." University of Kentucky law professor Joshua Douglas said the lawsuits "all seem to have no merit whatsoever". Bradley P. Moss, an attorney specializing in national security, wrote that the suits "continue to defy reason and logic, and are purely theater... It's all a farce". University of California, Irvine election law professor Rick Hasen said there is "no evidence of fraud so far that could conceivably affect the election results". Barry Richard, who helped to oversee the Republican-led Florida recount effort during the 2000 election, called the lawsuits "entirely without merit" and said they "will not be successful"; Gerry McDonough, an attorney who worked for the Gore campaign, said Trump "has no chance of overturning the result—it's just impossible". The Cybersecurity and Infrastructure Security Agency issued a statement calling the 2020 election "the most secure in American history" and noting "[t]here is no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised".

Jones Day, one of many law firms working for the Trump campaign and one that specifically handled Pennsylvania Democratic Party v. Boockvar, faced internal criticism for its "shortsighted" efforts on litigation that "erode[s] public confidence in the election results".

Summary of post-election lawsuits

The Trump campaign filed the most post-election lawsuits related to the 2020 United States presidential election in the swing states of Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin. It was a strategic decision to file lawsuits in these states that were too close to call during the night of election day and remained uncalled for a few days.

Counts Tally showing the number of lawsuits, sorted by state, that were dropped by plaintiff before a ruling, ruled against the plaintiff or dismissed by the court: this applying to all of the lawsuits filed by Trump and his supporters. The cases indicated to be ongoing refer to Michigan Welfare Rights Org. et al. v. Donald J. Trump et al.; several cases filed against Trump and other defendants in the aftermath of the January 6, 2021, attack on the Capitol, variously brought by members of Congress, United States Capitol Police officers, and District of Columbia Metropolitan Police officers; and two criminal cases, The State of Georgia v. Donald J. Trump, et al., a racketeering case against Trump and 18 other defendants, and United States v. Donald J. Trump, an election obstruction case. Of those cases, all but Georgia v. Trump were filed in the U.S. District Court for the District of Columbia. The one verdict in Pennsylvania ruled initially in Trump's favor, was after appeal, reversed by the Pennsylvania Supreme Court against the decision of the Commonwealth Court affirming the decision of the state's Court of Common Pleas reinstating the decision of the Allegheny County Board of Elections to count 2,349 ballots. Thus making the total ruled in favor for the Trump campaign in Pennsylvania 0 and total ruled against 2.
