Jack Smith Moves to Dismiss Trump’s Jan. 6 and Documents Cases

The special counsel Jack Smith asked two courts on Monday to effectively shut down the federal criminal cases he brought against President-elect Donald J. Trump last year, bowing to a Justice Department policy that says it is unconstitutional to pursue prosecutions against sitting presidents.

The twin requests by Mr. Smith — made to judges in Washington and Atlanta — were an acknowledgment that Mr. Trump will re-enter the White House in January unburdened by federal efforts to hold him accountable through charges of plotting to subvert the last presidential election and holding on to a trove of highly classified material following his first term in office.

The double-barreled filings were also the latest sign that Mr. Smith and his team were working to close up shop after years of intensive investigation and courthouse drama that tested the justice system’s ability to hold a once-and-future president to account amid shifting politics, misinformation and evolving legal standards.

Hours after Mr. Smith submitted his requests, Judge Tanya S. Chutkan, who is overseeing the election interference case in Washington, issued a brief order dismissing the proceeding.

Mr. Smith’s moves came after the president-elect began filling out his choices to lead the Justice Department. They followed Mr. Trump’s vow on the campaign trail to fire Mr. Smith within “two seconds” of taking office and to launch investigations into the prosecutors who pursued him, along with other perceived enemies. Mr. Smith has signaled that he intends to resign before Mr. Trump takes office.
