It’s only been a few weeks since Robert F. Kennedy Jr unveiled his running mate to America. But already Nicola Shanahan, a former patent lawyer and ex-wife of Google co-founder Sergrey Brin, is facing some heat.

Worried about the threat posed by the Kennedy-Shanahan ticket to Joe Biden’s re-election, Democrat operatives are said to be digging for dirt on the potential next Veep. According to a new report in Semafor, former Bill Clinton adviser James Carville has been calling various Silicon Valley figures for some opposition research. This comes after Shanahan tweeted out a message from CBS, in which she claimed to have been pressured by Democratic Congressman Ro Khanna to reconsider her support for RFK.

Shanahan says that she is not a “public person”, but politics may force her to start playing dirty too.
