In the year and a half that Donald Trump was running for president, he would often make headlines for his controversial and outlandish tirades on Twitter. After Trump sent out a questionable tweet to end 2016, celebrities were quick to offer their response as the year came to an end.

Trump's Twitter backlash.

On Saturday morning, Donald Trump sent out a Happy New Year Twitter message, but made sure to take a shot at his "many enemies" in the process. Over the next few hours, the billionaire real estate mogul sent out a multiple messages on social media, with most being basic well-wishes and retweets from his family and transition team.

As 2016 came to close and 2017 kicking off a new year, various celebrities took to their own Twitter accounts on December 31 and January 1 to voice their opposition.

"Donald Trump is that strange person you sorta knew from high school who overposts," "Star Trek" actor George Takei tweeted out, while adding "You want to tell them to stop, but it's pretty hopeless." In response to a recent Washington Post article questioning Trump's financial ties to Russia, actor and filmmaker Rob Reiner gave his thoughts.

"I applaud The Wash. Post for raising questions of DT's $ ties to Russia, Reiner tweeted, stating, "If treason exists, we need to know. Media and electeds-stay focused."

Filmmaker Michael Moore, who hit back at Donald Trump for his earlier New Year's Even tweet, expressed his relief that 2016 was now in the past, tweeting, "Whew.

Well THAT's over! Yay. It can only get better now." The hits kept coming against Trump, who has vowed to be the president of all Americans, but continues to be criticized for allegedly dividing the country even further.

Moving forward

Despite the growing backlash against his administration and agenda, Donald Trump is now just three weeks away from becoming the 45th President of the United States.

While the former host of "The Apprentice" prepares for Inauguration Day, as many as 100,000 protesters are planning to take to the streets in Washington, D.C. to air their grievances and make their opposition known to the new commander in chief.
