Trump, the first speaker Friday morning at the Conservative Political Action Conference (CPAC), spoke to a half-full ballroom as the audience trickled in for the next speaker, Senate Majority Leader Mitch McConnellMitch McConnellShutdown risk grows over Flint Senate poised to override Obama veto Overnight Finance: Four days left to avert shutdown | Conservative group bucks spending bill | Lawmakers play catch-up on smartphone banking MORE (R-Ky).
CPAC organizers have drawn some criticism for inviting Trump to speak while snubbing others like New Jersey Gov. Chris Christie (R).
The audience didn't seem very excited about the "Apprentice" host, though he received a warm welcome and drew applause for saying the U.S. should have taken from Iraq's oil reserve to pay for the war there.
Trump also blasted current immigration reform plans, attacking the idea of giving the mostly Hispanic and Asian population of illegal immigrants a pathway to citizenship.
"When it comes to immigration, 11 million illegals will be voting Democratic. You could say you are looking at a suicide mission," Trump said to applause. "Why aren't we letting people in from Europe?"
