Former President Donald Trump spoke at the Conservative Political Action Conference (CPAC) on Sunday, after a delay of at least a half hour from his scheduled starting time.
He was greeted by "USA" chants as he walked on stage, and lauded the CPAC attendees as strong supporters of his movement.
"With the help of everyone here today, we will defeat the radical left, the socialists, Marxists and the critical race theorists," Trump said. "We will secure our borders, we will stop left wing cancel culture, we will restore free speech and free elections and we will make America great again."
Trump added that "the people in this room have been some of the staunchest and fiercest supporters" of "the greatest political movement in the history of our country."
Trump Sunday also touted the actions he took as president, especially stringent immigration policies, and slammed President Biden for his handling of the border.

TRUMP EASILY WINS CPAC 2024 GOP PRESIDENTIAN NOMINATION STRAW POLL
"We deported criminal aliens by the thousands ... and we built almost 500 miles of the border wall," Trump said. "Now the Biden administration has turned the border into the single greatest disaster in American history."
The former president spoke at the Orlando CPAC event in February and used his speech to attack President Joe Biden, Republicans who have not been loyal to him and to hint at a potential 2024 presidential run.
The Dallas CPAC event continues Trump's continued resurgance into Republican politics after leaving the White House in January. Since the Orlando event Trump has made several major public speeches, including a recent one in Ohio supporting his former aide Max Miller in his campaign to unseat Rep. Anthony Gonzalez, R-Ohio.
Also since the February event, the GOP has moved closer and closer to Trump after some in the party distanced themselves from him in the wake of the Jan. 6 attack on the Capitol by a mob of his supporters.
House Minority Leader Kevin McCarthy, R-Calif., has worked to smooth over tensions within the party and get Trump on board to help House Republicans in 2022. And the House GOP Conference jettisoned Rep. Liz Cheney, R-Wyo., as their chairwoman over her denunciations of Trump's false claims that the presidential election was stolen.

Trump Sunday doubled down on his false claims that the election was stolen, and attacked social media platforms and news organizations for allegedly suppressing claims of widespread election fraud.
"You say election fraud you get cancelled," Trump said.
"Unfortunately this was an election where the person that counts the vote was far more important than the candidate," Trump said, continuing to allege widespread voting fraud without evidence. "It's a disgrace to our nation and we are truly being scorned and disrespected all over the world."
The former president also mentioned his lawsuit against big tech companies over alleged censorship of conservatives on their platforms.
"They are hard at work to abolish the First Amendment as well," Trump said. "The radical left and big tech's attack on free speech is unlawful , it's unconstitutional and it is completely unamerican."
"To protect the Constitutional rights and liberties of every citizen this week I filed a major class action. A lot of people are joining," Trump said to a standing ovation.
