During a press conference on Tuesday, White House Press Secretary Sean Spicer addressed the ongoing issue with Syria and compared Syrian President Bashar al-Assad to Adolf Hitler. During his response to reporters, Spicer made the critical error of falsely claiming that Hitler never used chemical weapons on the Jewish people in the Holocaust, which resulted in instant backlash.

Hollywood on Spicer

Ever since taking on the role of White House Press Secretary earlier this year, Sean Spicer has suffered the same fate as many other advisers and associates in the Donald Trump administration. Following in the footsteps of the former host of "The Apprentice," Spicer and others have made comments that often leave many scratching their heads.

From Kellyanne Conway's "alternative facts" and "Bowling Green Massacre" remarks, to Steve Miller's weekend of destruction, Spicer is also prone to verbal blunders. When Spicer spoke to the press on Tuesday, he made the aforementioned comparison of Assad to Hitler, while also referring to concentration camps as "Holocaust centers." The response to Spicer's comments were so negative that he was forced to issue an official apology, but that didn't stop numerous Hollywood stars from lashing out on Twitter on April 11.

"If donuts were awarded for dumb, Sean Spicer would have his own Krispy Kreme franchise," author Stephen King wrote on Twitter.

In a follow-up tweet on Tuesday night, King added, "But seriously--Spicer's level of lazy ignorance is representative of the whole Trump administration, starting with Golden Boy himself."

"Well, yesterday Pepsi was grateful for United, and today United is grateful for Sean Spicer," actor George Takei posted on his Twitter feed. "Jews at Seders will ask:"Why is this night different from all other nights?" Answer:"Nothing, there are still anti-Semites in the WH," actor and director Rob Reiner tweeted out.

"Kids to Sean Spicer: "Daddy! Daddy! Can we go to the Holocaust Center?! I want to go on one of the rides! Will they have cotton candy?!" filmmaker Michael Moore added with humor on his Twitter account.

Actress Alyssa Milano sent out a series of re-tweets using the hashtag "#FireSpicer," while also writing "You know it's bad when...." and attached a news story were conspiracy theorist Alex Jones was even critical of Spicer.

"Rather than a wall, America should build a giant mirror, to reflect what we have become," actress and singer Bette Midler wrote. Actress and talk show host Rosie O'Donnell also chimed in, adding "on Passover no less." MSNBC host Lawrence O'Donnell gave his thoughts on the situation, posting, "Sean Spicer is a profoundly stupid liar working for a profoundly stupid liar."

As the negative reactions continued to pour in, others took their opposition to the next level. The Anne Frank Center released a scathing statement on the incident, calling on Donald Trump to fire Sean Spicer, which was also echoed by House Minority Leader Nancy Pelosi.
