House Minority Leader Kevin McCarthy, who faulted the former president for his role in the attack and at one point considered asking him to resign, credited Trump at the annual Conservative Political Action Conference with helping Republicans with their surprise gains in the House a year ago.
"Do you miss me yet?"
Trump criticized by name fellow Republicans who voted to impeach him after the Capitol insurrection, and he stressed that the party's rank and file is with him.
During an appearance on CBS' "Face the Nation," McDaniel said that GOP voters would determine the fate of Trump's influence in the party, but stressed that party voters still supported his agenda.
While he insisted the division was merely a spat "between a handful of Washington, D.C., establishment political hacks and everybody else, all over the country", Trump had a message for the incumbents who had dared to cross him: "Get rid of 'em all".
CPAC is an event organised by the American Conservative Union, whose chairman, Matt Schlapp, is close to Mr Trump.
Former U.S. President Donald Trump is set Sunday to stake his claim as the dominant Republican in the country, trying to win back party control of Congress next year and possibly run again for the presidency in 2024.
Trump and his allies spent two months denying his election defeat, and claiming without evidence it was the result of widespread voter fraud, before his supporters stormed the Capitol on January 6 seeking to disrupt congressional certification of Biden's win.
Trump will deliver a Sunday afternoon speech - one in which he is expected to continue to falsely claim that the presidential election was stolen - that will mark his first public comments since leaving the White House.
"As you know, they just lost the White House", he said of Biden, rewriting history.
Major figures from the Trump cabinet - at least, those still loyal to the former president - were given speaking slots: Pompeo, former U.S. Trade Representative Robert Lighthizer, former acting Director of National Intelligence Ric Grenell and former budget director Russ Vought.
Research confirms that devotion to Trump among Republicans is similar to that reserved for a cult leader.
He sought to position himself as the lead critic of the new president, including on immigration and security along the USA border with Mexico, and the slow reopening of schools closed due to the pandemic.
The former President is expected to speak at CPAC later this weekend.
Donald Trump, in his speech, called for unity in the Republican Party, rejecting the possibility of forming his own party.
In the weeks since he criticized Trump over the deadly January 6 attack, McCarthy has scrambled to patch up his relationship with the former president, visiting him at his home in Florida and welcoming him to play a continued role in the party.
"Instead, we will be united and strong like never before". "It's going to unite and be stronger than ever before". Before she spoke, dozens of CPAC attendees, many of them young Republicans, waited in line to get her autograph. "We will save and strengthen America and we will fight the onslaught of radicalism, socialism and indeed, it all leads to communism", said Trump, who spent much of his speech hitting out at US President Joe Biden.
"And I wonder who that will be", he offered.
