[WASHINGTON] Presumptive Democratic presidential nominee Hillary Clinton met with Senator Elizabeth Warren on Friday morning as the two step up their political attacks on Republican standard-bearer Donald Trump.
The meeting at Mrs Clinton's Washington, DC, home comes one day after Ms Warren joined President Barack Obama in endorsing Mrs Clinton, who had clinched the nomination over liberal rival Bernie Sanders.
The women discussed how to work together to advance progressives' agenda and stop Mr Trump, and Mrs Clinton thanked Ms Warren for her endorsement, said a Clinton campaign official who asked not to be named. Ms Warren left Mrs Clinton's residence without commenting.
The support of Ms Warren, a Massachusetts senator, could help Mrs Clinton rally progressive voters who favored Mr Sanders in the primary. Mrs Clinton will seek Ms Warren's input, including on Wall Street regulation, the candidate said in a Bloomberg Politics interview on Thursday.
Amid speculation Ms Warren could become Mrs Clinton's running mate, Mrs Clinton said in a separate Politico interview Thursday that Ms Warren was qualified for any post.
Mrs Clinton has previously said the US may be ready for a two-woman ticket and that she'll focus on qualifications in her vice-presidential search.
Ms Warren told MSNBC Thursday she wasn't being vetted for the job but felt qualified for it as she announced her endorsement of Mrs Clinton.
"I am ready to get into this fight and to work my heart out for Hillary Clinton and to make sure that Donald Trump doesn't get anywhere near the White House," Ms Warren said.
The move by the first-term lawmaker, who many had urged to enter the 2016 race herself, came on the same day Mr Obama formally endorsed Mrs Clinton in a bid to unify Democrats following a White House meeting with Mr Sanders.
Vice President Joe Biden also quietly endorsed Mrs Clinton in a speech on Thursday night, saying "God willing," the next president would be Mrs Clinton.
Ms Warren could be an important foil against the Trump campaign.
After Mrs Clinton on Thursday responded to a Twitter insult from Mr Trump with the social-media joke "Delete your account," Ms Warren followed up Friday.
Mr Trump called Ms Warren a "goofy," unproductive senator with a "nasty mouth" and said he hoped she would be Mrs Clinton's running-mate choice. Ms Warren replied, "No, seriously - Delete your account."
