After just six months in the White House, Donald Trump is facing non-stop criticism that is taking place on a daily basis. Following the latest news that he's now under investigation, the president decided to lash out on social media.

Trump on Twitter

It all started back in June 2015 when Donald Trump made his way to the floor of Trump Tower in New York City to announce that he was going to run for president. Since then, the former host of "The Apprentice" has changed American politics, and depending on your political affiliation, did so for the better or for the worse.

In the last two years, Trump's policy proposals and controversial rhetoric have kept him in the headlines, but no one issue has remained a thorn in his side like the growing scandal involving Russia. The speculation over Trump's possible link to the Kremlin started early on when he refused to release his tax returns. Questions continued to be raised after the billionaire real estate mogul went on to praise Russian President Vladimir Putin, taking an even more dramatic turn as members of his campaign and administration were eventually found to have had their own ties to Russia. One of the latest twists to the story links back to Robert Mueller, the former FBI director who is now the special counsel to the investigation into Russia.

On Wednesday, the Washington Post reported that Mueller was investigating the president on allegations of potential Obstruction Of Justice. As seen during a June 15 tweet, Trump has decided to break his silence on the issue.

Taking to Twitter on Thursday morning, Donald Trump addressed the obstruction of justice allegations by dismissing them as he has the entire Russian investigation.

"They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice on the phony story," Trump tweeted out, before adding, "Nice." It's not a surprise that the president gave his thoughts on the matter in a social media post, as Twitter has become his number one form of communication with his relationship with the media turning sour.

Not stopping there, Donald Trump followed up his denial with yet another tweet, this time claiming he was the victim of a "witch hunt." "You are witnessing the single greatest WITCH HUNT in American political history - led by some very bad and conflicted people!" he wrote, while using the hashtag "#MAGA."

Moving forward

While Donald Trump continues to deal with allegations that he and his administration are in cahoots with Russia, it doesn't look like the commander in chief is ready to come clean. Though it's not 100 percent confirmed that Trump and the Kremlin have been working together, the evidence doesn't look to be slowing down.
