It's no secret that celebrities out in Hollywood don't see eye to eye with Donald Trump. For comedian Bill Maher, there is no love lost between himself and the president.

Maher on Trump

Donald Trump's feud with the mainstream media and Hollywood stars started within minutes of his campaign announcement back in June 2015. Once the former host of "The Apprentice" referred to illegal immigrants from Mexico as "rapists" and "murderers," the majority of the press and celebrities were quick to lash out. In the months that followed, Trump's controversial rhetoric and unorthodox campaign style made him a prime target for criticism, while also become the constant butt of the joke for comedians and late night TV hosts.

On shows like "Saturday Night Live," Trump became a weekly target with actor Alec Baldwin playing the satirical role of the billionaire real estate mogul. On late-night TV, hosts like Jimmy Fallon and Stephen Colbert have taken their shots at the president, but none have been as consistent as Bill Maher. While Maher usually saves attacking Trump for his HBO show "real time with Bill Maher," which airs Friday night's on the network, the notable atheist decided to poke fun at the president and his supporters during a September 17 tweet.

Taking to his Twitter account on Sunday afternoon, Bill Maher highlighted the recent dysfunction between Donald Trump and his supporters after the president cut deals with high-ranking Democrats over a variety of issues.

"I see Trump fans mad at his DACA reversal still burning their MAGA hats and posting the video on line - its called The Douchebag Challenge!" Maher tweeted out.

Bill Maher's comments come just two days after he dedicated last Friday night's "Real Time" to the trouble brewing on the political right, with Donald Trump supporters appearing to bail on him.

Maher mocked the president for his supporters ditching their "MAGA" hats, while calling out supporters like Ann Coulter, Rush Limbaugh and others for attacking the president over his recent moves.

Moving forward

While Bill Maher and others take turns mocking and trolling the commander in chief, Donald Trump has big problems he must address in the White House.

With an approval rating that dropped to just 35 percent in the most recent round of polling, Trump is currently battling not just the Democrats, the media, and rival world leaders, but also the in-fighting within his own Republican Party.
