Michael Moore recently released a surprise documentary about president-elect Donald Trump, who was still just a presidential candidate at the time of the film's release. But being Michael Moore, his film was only the beginning of what he had to say about Trump as president. In a Facebook post long enough to be considered an op-ed and shared late Tuesday night, Moore revealed that he believes Trump "is gonna get us killed" during his presidency.

Moore's post focused on the myriad of ways it seems Trump is a national security risk, beginning with his refusal to attend security briefings. "A week has gone by since Donald Trump admitted he's only been to 'two or three' of his daily presidential national security briefings," Moore wrote.

Moore predicted in his post that a terror attack on the U.S. under Trump will occur—and that it will spell disaster. "So, my fellow Americans, when the next terrorist attack happens—and it will happen, we all know that—and after the tragedy is over, amidst the death and destruction that might have been prevented, you will see Donald Trump acting quickly to blame everyone but himself," he wrote. "He will suspend constitutional rights. He will round up anyone he deems a threat. He will declare war, and his Republican Congress will back him."

Moore went on to compare Trump's recklessness to that of George W. Bush, but he said Trump will be even worse. "It's one thing to have a president who was asleep at the wheel," he wrote. "But, my friends, it's a whole other thing to now have a president-elect who REFUSES TO EVEN GET BEHIND THE WHEEL!"

About 12 hours after first being shared, Moore's post has more than 33,000 reactions and about 17,000 shares on Facebook. Go here to check it out for yourself.
