After only one week in the White House, Donald Trump is facing heavier backlash than at anytime in his brief political history. After signing the controversial "Muslim ban" executive order, Trump's critics came out swinging, including actor Alec Baldwin.

Baldwin on Trump

Over the last year and a half, Alec Baldwin has appeared on "Saturday Night Live" and has played the part of a satirical version of Donald Trump. Baldwin's impression has received rave reviews, but has not gone over well with the former host of "The Apprentice." Trump has gone on multiple social rants about the show, blasting Baldwin as "not funny," while calling for "Saturday Night Live" to be canceled.

While Baldwin often mocks Trump with humor, he has gotten more serious at times when it comes to criticizing the new commander in chief. As seen on his offical Twitter account on January 29, Baldwin is not happy with Trump's recent moves in office.

"1- This country had a calling card.

We all knew what it was. It wasn't Wall Street or Hollywood or the right to bear arms that brought," Alec Baldwin wrote on his Twitter account. In his second tweet, the actor added, "2- that brought countless people, America's future, to this country. It was freedom. Freedom was our calling card. Trump wants to kill that." Making his third point, Baldwin kept it short and sweet, stating, "3- Trump's gotta go."

Just two hours later, Alec Baldwin went back to Twitter to express his disdain for Donald Trump.

"All the indignation is fine. But we gotta get him out!," he wrote, while adding, "We must demand a competency test! He is ill! Mentally ill!" On Sunday morning, Baldwin once again used Twitter, this time with a bit more humor to attack the new president.

Fighting back with humor

"When I travel back to the US, I hope they have a box for me to check that reads "Muslim Irish Catholic,'" Alec Baldwin wrote.

Baldwin, and millions more across the country, have lashed out over Trump's executive order referring to the aforementioned "Muslim ban." As of press time, a federal judge has issued a temporary "stay," though it's unknown how long it will last. In response, Trump used his own Twitter account to defend his executive order, citing safety concerns for the American people.
