RFK Jr. Received $2 Million From His Running Mate, Nicole Shanahan

As Robert F. Kennedy Jr.’s independent presidential campaign ran up debts and spent heavily on ballot access, security and consultants, he received a lifeline at the end of March in the form of a $2 million cash infusion from his newly minted running mate, Nicole Shanahan, a new campaign filing shows.

Mr. Kennedy’s campaign reported raising $5.4 million in March, including the money from Ms. Shanahan, which was recorded on March 27 — the day after he announced her as his running mate.

The campaign reported spending $4.5 million in March, an increase from the previous month, and listed $1.6 million in debts, all of which were payments owed to Mr. Kennedy’s security consultant, Gavin de Becker, the filing to the Federal Election Commission shows.

The campaign ended the month with $6 million on hand, the filing shows.

Under federal law, candidates can inject unlimited money into their own campaign, and are not subject to the $6,600 individual limits for general-election contributions. Ms. Shanahan, a wealthy Silicon Valley lawyer and investor, was until last year married to the Google co-founder Sergey Brin.
