Washington (CNN) Ret. Maj. Gen James "Spider" Marks said Thursday that Hillary Clinton will do a better job defending the country and the Constitution than Donald Trump.

"What I care about is national security first and foremost," Marks, a CNN military analyst, told CNN's Erin Burnett on "Erin Burnett OutFront." "This is first and foremost. It's the job of the president of the United States, of our commander in chief, to defend the Constitution. I want that done right. I think that Hillary Clinton will do that better than Donald Trump."

He said that he is planning to vote for Clinton for president in November.

"I made that decision," he said. "I have been wrong so many times ... You don't see that level of humility in this candidate (Trump). That's what bugs me. I'm not a big fan of where we are right now with this current administration."

Earlier on the show, Marks denounced Trump's claim that President Barack Obama founded ISIS, calling it "crazy talk."
