Former VP Joe Biden has reportedly asked Senator Amy Klobuchar to undergo vetting to be a potential running mate, according to a source with knowledge of the discussion.

The source did not provide details on the discussion. A spokesperson for the Biden campaign declined to comment on the matter. 

It’s not yet clear if Klobuchar has consented to the vetting, which would delve deep into her private and public life to uncover any potential weaknesses or vulnerabilities as a vice presidential candidate. The vetting process will be handled by a select committee led by former Senator Chris Dodd, Representative Lisa Blunt Rochester, Los Angeles Mayor Eric Garcetti and longtime Biden adviser Cynthia Hogan. 

If Biden chose Klobuchar as his running mate, he would add a fellow moderate to the Democratic ticket — a move that may help win over some independents and centrists, but one that would almost certainly anger liberals, who are pushing Biden to choose a progressive as his running mate.

Norman Solomon, long-time activist, currently advising the progressive political action committee ‘Once Again PAC’, said that it would be a mistake for Biden to choose Klobuchar as his running mate, arguing that it would upend his efforts to unite the Democratic Party.

“Someone like Klobuchar is anathema to broadening the ticket,” Solomon said in a recent interview. “If Biden is serious about unity then he’s got to pitch a tent big enough to include progressives.”

Klobuchar has support among some centrist Democrats on Capitol Hill. Representative Dean Phillips, a moderate Minnesota Democrat like Klobuchar, says-

“As a party that is increasingly portrayed as one for both coasts, I think there’s something quite powerful about a vice presidential candidate from the Heartland,” Phillips told The Hill, noting that others on the VP short-list hail from California, Massachusetts and other coastal states. “I do think that there’s a big part of this country that is looking for someone that kind of feels like they know them, represent them and understand them, and Klobuchar really does.

“I think the middle of America is longing for that kind of representation on both sides of the aisle,” he added.

Biden’s decision on a running mate is still likely weeks away.
