Robert F. Kennedy Jr. is expected to announce his VP pick for his third-party White House bid

OAKLAND, Calif. (AP) — Robert F. Kennedy Jr. plans to announce his running mate Tuesday as he races to secure a place on the ballot for his independent campaign for president.

In advance of an event Tuesday in Oakland, Kennedy and his aides have circulated the names of several contenders, including celebrities with household names and no experience in politics. Those names include NFL quarterback Aaron Rodgers and “Dirty Jobs” star Mike Rowe as well as former Minnesota Gov. Jesse Ventura. Speculation most recently has centered on Nicole Shanahan, a lawyer and philanthropist who bankrolled a Super Bowl ad for Kennedy.

“This announcement is really going to shake up the political establishment,” Kennedy said in a video he posted on social media last week.
