Former President Donald J. Trump on Tuesday made a slashing and lengthy attack on Senator Mitch McConnell, the Republican minority leader, calling him a “dour, sullen, and unsmiling political hack” and arguing that the party would suffer losses in the future if he remained in charge.
“If Republican senators are going to stay with him, they will not win again,” Mr. Trump said.
The 600-word statement, coming three days after the Senate acquitted him in his second impeachment trial, was trained solely on Mr. McConnell and sought to paint Mr. Trump as the best leader of the G.O.P. going forward. The statement did not include any sign of contrition from Mr. Trump for his remarks to a crowd of supporters who then attacked the Capitol on Jan. 6. Nor did it include any acknowledgment of his role during the violent hours in which his own vice president and members of Congress were under threat from the mob of Trump supporters.
Rather, Mr. Trump chose to focus on Mr. McConnell as he broke an unusually lengthy silence by his standards, after being permanently barred from his formerly favorite medium — Twitter — last month because of tweets that he posted during the Capitol riot.
Shortly after he joined the majority of Republican senators on Saturday in voting to acquit Mr. Trump on the House impeachment charge of “incitement of insurrection,” Mr. McConnell excoriated Mr. Trump, laying the blame for the deadly riot at his feet and suggesting that further investigations of the former president could play out in the judicial system.
Those comments were widely interpreted as an attempt to minimize Mr. Trump’s brand of politics within the Republican Party, and to appeal to donors who have said they are rejecting the party after some senators voted against certifying President Biden’s victory.
Mr. McConnell wrote a Wall Street Journal op-ed article and gave an interview to the paper’s news section suggesting he might get involved in primaries for 2022 as part of an effort to win back the majority. Representatives for Mr. McConnell did not immediately respond to requests for comment on Tuesday.
