Trump on Twitter

Donald Trump has created a constant stream of controversy ever since he first announced his plan to run for president over two and half years ago. Due to his reckless rhetoric and questionable policy proposals, it was expected that most Democrats and members of the mainstream media would push back, but it's been a surprising number of Republican critics that have caught many off guard.

It's become common place for Trump to call out high-profiled Republican names across social media, with Sen. John McCain and Senate Majority Leader Mitch McConnell being at the top of the list. Recently, Trump has engaged in a heated war of words with Sen. Bob Corker who has been critical of the president ever since announcing that he wouldn't run for another term. On Tuesday, Republican Sen. Jeff Flake came forward and also revealed that he would follow in Corker's footsteps and leave congress because of Trump being in the White House. "I just can’t continue with this kind of politics," Flake said. As seen on his Twitter account on October 25, Trump has gone on the attack.

Taking to his Twitter feed on Wednesday morning, Donald Trump was quick to lash out at Jeff Flake and Bob Corker.

"The reason Flake and Corker dropped out of the Senate race is very simple, they had zero chance of being elected," Trump tweeted, before adding, "Now act so hurt & wounded!"

"The meeting with Republican Senators yesterday, outside of Flake and Corker, was a love fest with standing ovations and great ideas for USA!" Donald Trump added in his second post on the issue.

In his third and final tweet on the matter, the president doubled down on his attack against Jeff Flake. "Jeff Flake, with an 18% approval rating in Arizona, said 'a lot of my colleagues have spoken out,'" Trump wrote, while concluding, "Really, they just gave me a standing O!"

Moving forward

While Donald Trump continues to fight with members of his own Republican Party, the commander in chief has many other issues facing him in the White House.

With an approval rating of just 35 percent, Trump has an uphill battle to climb when it comes to health care and tax reform, as well as foreign policy matters, most notably the current rift with North Korea.
