More than 800 donors packed into a Westin Diplomat Hotel ballroom Thursday night to pad Barack Obama’s war chest by another $500,000, according to this pool report of the evening.

In a speech to the crowd, Obama sharpened his rhetoric against some of the most vocal voices against immigrant workers and migrant worker programs.

“A certain segment has basically been feeding a kind of xenophobia. There’s a reason why hate crimes against Hispanic people doubled last year,” Obama said. “If you have people like Lou Dobbs and Rush Limbaugh ginning things up, it’s not surprising that would happen.

Politico's Jonathan Martin writes that Limbaugh addressed Obama's remarks on his radio show today and said that the remarks hurt his feelings.

"I actually don't believe this. Barack Obama, in my own state, raising money for his presidential campaign called me xenophobic at a fundraiser," Limbaugh said. "I thought this guy was the unity candidate? Calling me a Xenophobe? Responsible for hate crimes? My feelings are hurt here."

Earlier this year, promoting his book "His Panic: Why Americans Fear Hispanics in the U.S.," Geraldo Rivera called Dobbs a "hate-monger" and said "I would not shake his hand because this is a man that's done more damage to the cause of sensible, comprehensive reform than anyone with a microphone."
