Liberal filmmaker Michael Moore advocated for the impeachment of President Donald Trump in a lengthy Facebook post this week.

"IMPEACH! It is time to remove this dangerous man from office," Moore wrote. "I have just signed the 'Need To Impeach' petition initiated by Tom Steyer of California. Over two million other Americans have also signed it. And that number keeps growing every hour. We — all of us — must not wait a minute longer to act."

Moore listed a series of reasons why he feels like Trump should be removed from office, including sending ships to the Korean peninsula in what Moore feels is a way to get the United States into a war and overshadow the Russia investigation.

He noted that having Trump occupy the Oval Office is "the most colossal mistake in our history. … And there is only one way to rectify it: TRUMP MUST BE IMPEACHED.

"We can NOT wait until November of 2020 for that to happen. We simply won't make it 'til then. The country we know as the United States of America will not be the same after three more years of Trump. You know it and I know it. Turning the TV off and trying to avoid the daily insanity won't make him go away."

Moore has been a Republican critic for years. Most recently, he put on a one-man Broadway show in which he bashed Trump. The show, however, earned less than 50 percent of its potential gross.

In his Facebook post this week, Moore called Trump "a malignant narcissist and an active sociopath" and said he has lied about his finances.

Moore also hit back at Senate Democrats for not standing on the chamber floor and calling for Trump's impeachment.

"They need to hear from us! Now! If recent history has proven anything, it's that Democrats only act when we tell them to," Moore wrote.
