Trump impeachment: on Immigration

Charles Djou: Leaving GOP because Trump makes it hostile to immigrants

"Today, after much consideration, I abandon my party because I am unwilling to abandon my principles. I can no longer stand with a Republican Party that is led by a man I firmly believe is taking the party of Lincoln in a direction I fundamentally disagree with, and a party that is unwilling to stand up to him.

"I have long believed that America's strength lies in our nation's diversity--not its exclusion or isolation. We are a nation of immigrants and benefit from a national fabric woven with the threads of many people, of many backgrounds and cultures, all united in the common belief and love of American liberty. That's why I championed immigration reform as a congressman.

"It disturbs me that the Republican Party under President Donald Trump is now defined as a party hostile to immigration. We are the leader of the free world, not because we are great (or need to be great again), but because we are good."

"They can't believe that we're making such an effort to cease immigration coming into the country. It's what's kept us alive," he said. "How can we be walking away from this model?"
