Here's the Trump campaign response.
President Obama did not hold back.
In a press conference Tuesday, he said bluntly, "The Republican nominee is unfit to serve as president."
I said it last week, and he keeps on proving it.
The remark came after Trump's highly controversial comments on the family of Capt. Humayun Khan, who was killed in Iraq in 2004.
He also called on Republican leaders to join him in denouncing Trump, saying their condemnations of the Khan comments "ring hollow" if they continue to endorse him.
