Sen. Elizabeth Warren (D-MA) confirmed on Thursday night that she would endorse Hillary Clinton in the presidential race.

"I am ready," Warren told MSNBC host Rachel Maddow. "I am ready to get in this fight and work my heart out for Hillary Clinton to be the President of the United States."

Warren announced her endorsement of the former Secretary of State shortly after a speech describing the presumptive Republican Party nominee, Donald Trump, to House Speaker Paul Ryan (R-WI) and Senate Majority Leader Mitch McConnell (R-KY), arguing that the real estate magnate's anti-immigrant and anti-Muslim rhetoric does not fall outside of the GOP's wheelhouse.

"Hillary Clinton won. And she won because she's a fighter, she's tough, and this is what we need," said Warren, who has also reportedly been the subject of an inquiry by Senate Minority Leader Harry Reid (D-NV) as to how to maintain her Senate seat after being tapped as a running mate for Clinton. However, Warren said she had not spoken to Clinton about being her vice-presidential candidate.
