Hillary Clinton is 'vetting' Elizabeth Warren as running mate, according to reports

Two women on the ticket? Senator Warren’s policies are closely aligned with Bernie Sanders

Hillary Clinton is actively looking at Massachusetts senator Elizabeth Warren as running mate and vice president of her possible future administration in January 2017.

As reported by the Wall Street Journal, Ms Warren is being “vetted” for the position rather than senator Bernie Sanders, Ms Clinton’s rival who has vowed to hold a contested party convention next month.

Ms Warren’s policies are closely in line with that of Mr Sanders, however, being mostly populist and progressive.

She is known for her strong stance on Wall Street regulation and has not minced her words when attacking Donald Trump.

She called him a “small, insecure money grubber” who will “never be president”, in response to his remarks that she was “goofy” and “Pocahontas” for “lying” about her Native American heritage.

Ms Warren endorsed Ms Clinton last week after the latter swept up the majority of the votes in the final round of democratic state primaries, clinching the number of delegates she needed to become the presumptive nominee.

“I am ready to get in this fight and work my heart out for Hillary Clinton to become the next president of the United States — and to make sure that Donald Trump never gets anyplace close to the White House,” she told MSNBC.

The partnership would be the first time in history that two women are on the ticket for president and vice president.

The pair met last Friday at Ms Clinton’s Washington DC home, fueling rumours that Ms Warren will be announced as the running mate.

Ms Warren's latest concern has been to advocate the banning of assault weapons after the mass shooting in Orlando and showing solidarity with the LGBT community.

The vetting process for candidates, which also includes Housing and Urban Development Secretary Julián Castro, Senator Sherrod Brown of Ohio, and Los Angeles Mayor Eric Garcetti, is limited to scrutinizing public information and has not yet asked them to submit their tax returns and other personal information.

Media commentators have suggested Ms Clinton has no plans to include her rival Mr Sanders on the candidate list, although Mr Sanders said last Thursday after meeting president Barack Obama that he “looked forward to working with” the secretary of state to defeat Mr Trump.
