Elizabeth Warren says she'll run for re-election — to fight Trump more

Donald Trump will be the next U.S. president, but Sen. Elizabeth Warren's feud with him isn't over.

The Massachusetts Democrat officially announced her re-election bid Friday, but in doing so, she also continued to wage war with Trump.

"The people of Massachusetts didn't send me to Washington to roll over and play dead while Donald Trump and his team of billionaires, bigots and Wall Street bankers crush the working people of our Commonwealth and this country," Warren said in an email to supporters Friday.

"In the weeks and months ahead, we will stand up to the Trump Administration's racism, sexism, bigotry and hate," Warren said. "We will fight back against attacks on Latinos, African-Americans, Muslims, immigrants, women and LGBT Americans. Our diversity is what makes our country strong — and on this, there will be NO compromise."

Warren and Trump notoriously clashed during the 2016 campaign, trading jabs and demeaning nicknames.

Trump repeatedly referred to Warren as "the Indian" and "Pocahontas" in reference to her self-proclaimed Native American ancestry. Warren has claimed to be a descendent of Cherokee and Delaware Indian, inviting speculation and scrutiny.

Avid Twitter user Trump also referred to Warren often as "goofy."

Warren, too, was no stranger to Twitter during the campaign, often taking the opportunity to respond to Trump's criticism or call him a "loser" or a "pathetic coward."

"I think he's a lot weaker than he wants to admit," Warren said of Trump in an interview in May.

Once widely speculated to be a potential running mate to Trump's campaign rival, Democratic presidential nominee Hillary Clinton, Warren instead served as a Democratic attack dog during the campaign.

Since Trump's election, Warren has continued to rail against the president-elect. In November, she criticized him for choosing "Wall Street insiders" to serve on his transition team.

And earlier this week, she joined other Senate Democrats in introducing legislation that would curtail tax breaks for Trump's Cabinet picks.

Warren told her supporters Friday that she expects fights in the Senate — and for her own reelection — to be "uglier and nastier" than before.

"The smears and right-wing attacks from Donald Trump, Mitch McConnell, the Koch Brothers and Wall Street aren’t about to get a little worse — they’re about to get A LOT worse," Warren said. "We cannot and will not allow the Republicans and the powerful interests to sink our campaign the same way they sank so many campaigns in 2016."

A challenger to Warren has not been formally announced, though former Boston Red Sox pitcher-turned-conservative-firebrand Curt Schilling has teased a potential bid for the seat.
