The former president did not say which crimes, if any, prosecutors specified in a letter notifying him that he may be indicted again.
In the two and a half years since a mob laid siege to the Capitol in an effort to prevent Congress from certifying Joseph R. Biden Jr.’s electoral victory, a wealth of evidence has emerged about Donald J. Trump’s bid to stay in power after the 2020 election.
Mr. Trump and his allies peddled spurious claims of voter fraud, pressured officials in states he narrowly lost and recruited false slates of electors in those states. He urged Vice President Mike Pence to delay certification of Mr. Biden’s win. And he called on a huge crowd of his supporters to march on the Capitol and “fight like hell.”
Now, Mr. Trump appears almost certain to face criminal charges for some of his efforts to remain in office. On Tuesday, he disclosed on social media that federal prosecutors had sent him a so-called target letter, suggesting that he could soon be indicted in the investigation into the events that culminated in the riot.
Mr. Trump did not say what criminal charges, if any, the special counsel, Jack Smith, had specified in issuing the letter.
But since the Capitol attack — in part because of revelations by a House committee investigation and news reports — many legal specialists and commentators have converged on several charges that are particularly likely, especially obstruction of an official proceeding and conspiracy to defraud the government.
Norman Eisen, who worked for the House Judiciary Committee during Mr. Trump’s first impeachment and contributed to a prosecution memo modeling potential Jan. 6-related charges, said that the target letter suggested the special counsel “has more than enough evidence” to bring a case against the former president.
“By leading the effort to procure fraudulent electoral certificates across the nation, Trump helmed a conspiracy to defraud the U.S.,” Mr. Eisen said. “And by using those false documents to press Mike Pence to disrupt the Jan. 6 meeting of Congress, Trump attempted to obstruct an official proceeding.”
There have also been signs that prosecutors have explored potential charges involving wire or mail fraud related to Mr. Trump’s fund-raising efforts in the name of overturning the election results.
Any charges in the District of Columbia — where federal grand juries have been hearing evidence — would raise additional legal peril for Mr. Trump. Already, the Justice Department has won guilty pleas or convictions in hundreds of cases related to the riot, suggesting that a pool of jurors may be less receptive toward him than in Palm Beach County, Fla., where he faces charges over his hoarding of sensitive government documents at his Mar-a-Lago estate.
