US Democratic Senator Elizabeth Warren has announced that she will run for the White House in the 2020 US presidential race, prompting a harsh response from President Donald Trump.

AVA- Warren, a 69-year-old lawmaker from Massachusetts, said in a video released to her supporters on Monday that she was launching “an exploratory committee for president” to fight what she called “corruption” in Washington.
A firm critic of Trump, Warren said the US government had been “bought and paid for by a bunch of billionaires and giant corporations that think they get to dictate the rules that affect everyone."
"That’s not how government is supposed to work," said Warren. "You know it. I know it. And we know it is time to fight back."
Although she did not name Trump even once during the video, her remarks seemed to concern the Republican head of state.
Trump reacted to the announcement by hurling yet another personal attack against the Democratic senator, whom he has repeatedly called “Pocahontas” in the past to mock her alleged Native American heritage.
Asked by Fox News whether he thought Warren could make him a one-term president and prevent his re-election in 2020, Trump said: "Well, that I don't know, you’d have to ask her psychiatrist."
"She did very badly in proving that she was of Indian heritage. That didn't work out too well," the president added, referring to a DNA test that Warren took last year to prove she was indeed a Native American.
The test, however, didn’t go as she had hoped as the DNA analysis showed most of Warren’s family tree is European and she could only be between 1/64 and 1/1,024 Native American.
"I think you have more than she does, and maybe I do too, and I have nothing," Trump told the interviewer Pete Hegseth.
The president went on to predict an easy win for himself in 2020.
"If you go just based on the record, I don't see how anybody [else] wins," he said. "It doesn't just seem based on the record that somebody's going to do really well."
Besides Warren, there is speculation that former US Vice President Joe Biden, Senator Kamala Harris of California, Senator Cory Booker of New Jersey and New York Senator Kirsten Gillibrand will also enter the 2020 Democratic field in the coming months.
