Mr Trump‘s eldest son, Donald Jr, told attendees his father’s speech will “solidify” his position “as the future of the Republican Party”.
Republican leaders in Congress who have suggested the party divest from Mr Trump, including senator Mitch McConnell and congresswoman Liz Cheney, have not been invited to the annual gathering. Ms Cheney was ridiculed by Mr Trump Jr in his speech.
In anticipation of Mr Trump‘s appearance, CPAC attendees have been posing with a gold-plated statue of him. His appearance will follow a presidential straw poll that he is widely expected to win.
Although the speech will underscore Mr Trump‘s dominance over the party and its future electoral hopes, aides suggest he is undecided over whether to run for a second term in 2024.
During his public hiatus, Mr Trump has formed a new political apparatus at his Florida base, hiring former campaign advisers and reportedly considering launching another political action committee (PAC) to raise cash and push his agenda.
His speech is likely to deepen the rift with ant-Trump Republicans pressing for a clean break before the next election.
“The only divide in the Republican Party is between the grassroots and a half a dozen … insiders,” Mr Trump is expected to say.
