Morning Joe calls on GOP to stop Trump before he starts WWIII: 'There's something called the 25th Amendment'

MSNBC's Joe Scarborough called out Republicans for remaining silent as President Donald Trump senselessly provokes World War III.

The "Morning Joe" host has been sounding the alarm about Trump's fascination with nuclear weapons since August 2016, when he revealed that the then-GOP nominee challenged foreign policy experts to explain why the U.S. could not use them in war.

"Every Republican senator on Capitol Hill has the record before them," Scarborough said. "Calling for a tenfold increase in nuclear weapons, having the most powerful Republican on Capitol Hill saying Donald Trump's erratic words and actions are leading us towards World War III."

He challenged Republicans to push back against the president's provocations.

"A delegation of Republicans need to go over the White House and tell the president, either you assure us that the chairman of the Foreign (Relations) Committee in the United States Senate is wrong or we are going to take immediate action to limit your ability to launch nuclear weapons," Scarborough said.

Gen. Michael Hayden warned last year, after "Morning Joe" reported Trump's desire to use nuclear weapons, that the process for launching the most destructive weapons in the world was a streamlined process that favored speed over rationality.

"These Republican senators in the middle of October 2017 have that responsibility for millions and millions of Americans and others across the globe, and if they can't do that, then there's something called the 25th Amendment that they're going to have to start looking at," Scarborough said. "This is not acceptable as the status quo. We have the most powerful Republican on Capitol Hill saying the president of the United States could be leading us toward nuclear war, and Republican senators remain silent."
