WASHINGTON, D.C. (CNN) – Donald Trump gave a major speech on the economy Monday, staying on message and remaining mostly calm, even when protesters interrupted him.
But Trump’s address may be overshadowed by the lingering effects of his series of controversies last week and the news of fresh opposition from within his own party.
“Donald Trump, I believe, is a real authoritarian. I believe he has no respect for our system. I believe he’s inhuman,” said presidential candidate Evan McMullin.
The former CIA staffer and top House GOP aide is now launching a conservative Independent White House bid.
“I don’t think that he cares about anyone but himself,” McMullin said.
He is the latest Republican to voice conservative frustration against Trump.
Just hours later, GOP Senator Susan Collins said in a Washington Post op-ed that she won’t be voting for Trump. Collins wrote that she is deeply concerned about, “Mr. Trump’s lack of self-restraint and his barrage of ill-informed comments.”
Also on Monday, 50 GOP national security experts signed a letter opposing Trump, writing that he, “Would be the most reckless president in American history.”
Two of those experts spoke to CNN Monday.
“He’s erratic, he overreacts, and that’s compounded, of course, by his utter ignorance,” said Dov Zakheim, former under secretary of defense.
“I think taking on a Gold Star father and a Gold Star mother probably was the low watermark of his campaign,” said Roger Zakheim, former deputy assistant secretary of defense.
Trump said in a statement that the letter came from, “The failed Washington elite looking to hold onto their power.”
The letter’s signatories rejected that accusation.
“It’s not sour grapes at all. It’s fear for the country – we fear for this country if that man gets into the White House. It’s as simple as that,” Dov Zakheim said.
