"It doesn't appear that I'm going to be the nominee, so I'm not going to be determining the scope of the convention," Sanders said during a taped C-SPAN interview ADVERTISEMENT Sanders said Clinton should pick "the most progressive candidate that she can find" to be her running mate. A handful of candidates, though not Sanders, are reportedly being considered

"I think it would be a terrible mistake to go to a candidate who has roots in Wall Street or was backed by Wall Street," he said.

Sanders met with Clinton on June 14 at a hotel in Washington just blocks from the White House but has yet to formally endorse the former secretary of State for president.

He has yet to also explicitly suspend his presidential bid, saying he'll push to leave a mark on the Democratic platform at the party's national convention in July.

Top Democrats, including President Obama and Vice President Biden, endorsed Clinton as their presumptive presidential nominee June 9 after her wins in the California and New Jersey primaries.
