"I hear President Biden saying 'America's back'. Back to what?" Pompeo said to an enthusiastic audience. "Back to President Biden killing a pipeline?" he asked.
House Minority Leader Kevin McCarthy also appeared on Saturday and told the gathering that the Republicans will surely win back the House in the 2022 mid-term elections.
"I would bet my house," he said during a short panel.
Trump is expected to talk on Sunday about the future of the party and lay out policy differences within a group riven by differences in the wake of his chaotic four years in office.
Many other senior Republicans did not attend this year's event. They included former Vice President Mike Pence and Senate Minority Leader Mitch McConnell.
Some advisers say they want Trump not to use his speech to re-litigate the 2020 election at length but instead offer a road map to Republicans' regaining control of the House of Representatives and the Senate in the 2022 congressional elections.
CPAC is an event organized by the American Conservative Union, whose chairman, Matt Schlapp, is close to Trump. It is a prime venue for speakers who want to gauge interest in whether they should run for president based on the enthusiasm they generate.
MIKE POMPEO: I hear President Biden saying, America's back.
Back to what? So-- back to-- back to pallets of cash to the Ayatollah, so he can build missiles that threaten us? Back to apologizing when Iranians tell our soldiers and sailors to take to their knees at gunpoint? And we certainly don't want to go back to letting China have trade deals that kill our jobs right here in America.
KEVIN MCCARTHY: Oh, excellent.
- I think we have a great chance of getting the majority back.
KEVIN MCCARTHY: Not a chance, we're going to get the majority back.
- There you go.
KEVIN MCCARTHY: We're five seats away.
[CHEERING AND APPLAUSE]
I would bet my house. Listen, we are-- we were [? 31,751-- ?]
- Wait, your personal house?
KEVIN MCCARTHY: [? --votes. ?] My personal house--
- You're not betting doll house, yeah.
KEVIN MCCARTHY: Don't tell my wife, but I would bet it. Listen, do you want to retire Nancy Pelosi?
- Oh yeah.
KEVIN MCCARTHY: Do you want to end the socialism in this country?
KEVIN MCCARTHY: Win the House, five seats, the closest-- this is the smallest majority the Democrats have had in 100 years. We could do it.
