It's no secret that Donald Trump has never been shy about voicing his opinion about any of his political critics. For Democratic Sen. Elizabeth Warren, the president doesn't look to be slowing down his own criticism.

Trump on Warren

It all started back in the summer of 2015 when Donald Trump caused a media frenzy on the floor of Trump Tower. With members of his family surrounding him, the former host of "The Apprentice" announced his campaign for president, and just minutes later dominated the headlines after labeling illegal immigrants from Mexico as "rapists" and "murderers." For the next two years, Trump faced an increased amount of backlash from his political opponents, with some of the most high-profiled Democrats speaking out against him on a daily basis.

One Democrat who has never held back her thoughts on Trump has been Massachusetts Sen. Elizabeth Warren. The progressive favorite has been more than vocal in holding Trump's feet to the fire during and since the election, with the senator ripping into the billionaire real estate mogul over his controversial policy proposals and executive orders, to the growing Russian scandal, and questionable rhetoric. In response, Trump has labeled Warren as "Pocahontas" after the senator appeared to embellish her ancestry as a Native American. Trump elaborated further on his thoughts on Warren during a June 25 interview on Fox News.

While joining Fox News host Pete Hegseth for an interview on Sunday's "Fox & Friends," Donald Trump was asked about his thoughts on Elizabeth Warren's recent criticism of his heath care bill and the controversy that resulted from his use of the name "Pocahontas" to describe her.

"I think she’s a hopeless case," Trump answered. "I call her Pocahontas," he continued, before explaining, "that's an insult to Pocahontas. I actually think that she's somebody that's got a lot of hatred, a lot of anger." Not stopping there, Trump added, "I watched her campaigning for Hillary and she was so angry." Some have accused the president of "racism" for his use of the name, but it doesn't' look to be slowing him down anytime soon.

Moving forward

While Elizabeth Warren and others continue to trade jabs with Donald Trump over a variety of issues, the president is currently backed into a corner.

With the scandal and investigation involving Russia heating up, Trump is also faced with having to pass his Health Care Bill, as well as other topics that look to be dividing the American people in and out of Washington.
