While Donald Trump is a member of the Republican Party, he's not been shy about calling out members on his own side when he sees fit. After first targeting Bob Corker on Twitter, the senator from Tennessee decided to responded, much to the chagrin of the president.

Trump on Corker

Not long after Donald Trump announced his plans to run for president in the Republican primary back in June 2015, members of the party were quick to keep their distance from the former host of "The Apprentice." Throughout the primary and later the general election, more establishment members of the GOP appeared uncomfortable with Trump leading the party into the future.

Following Trump's win over former Secretary of State Hillary Clinton last November, those who had reservations about Trump were forced to fall in line. However, Republican Sen. Bob Corker has not been one to hold back his thoughts in regards to Trump and the White House due to giving his notice that he would be retiring from Congress at the end of his term. With Corker increasing his criticism of Trump as of late, the president hit back at the senator during a series of tweets. Corker later replied, which resulted in the president firing back once again on October 8.

On Sunday morning, Donald Trump took to Twitter and accused Bob Corker of retiring only after he allegedly "begged" the president for his endorsement.

The commander in chief went on to blame Corker for voting for the Iran deal, which Trump has been highly critical of, before stating that he "didn't have the guts to run" for his re-election. Responding to Trump, Corker compared the White House to an "adult daycare center."

Just hours later and Donald Trump went back on the attack with another tweet.

"Bob Corker gave us the Iran Deal, & that's about it," Trump wrote. Not stopping there, Trump continued, tweeting, "We need Health Care, we need Tax Cuts/Reform, we need people that can get the job done!"

Moving forward

As Donald Trump continues his war of words with Bob Corker, the president has many other issues facing him in the White House.

The president has been unable to convince enough Republicans to approve his plans for health care and tax reform, while the rift between the United States and North Korea hangs in the balance of uncertainty. Trump's inability to move the chain on major issues has resulted in a historically low approval rating with the American people, which has dropped to just 35 percent in the latest polls.
