Bernard L. Barker, former member of the Cuban secret police under the Batista regime and subsequently one of the "Plumbers", the Nixon White House's so-called "Special Investigations Unit", was one of the five burglars paid by the Committee to Re-elect the President, Nixon's re-election campaign fundraising committee, and convicted in the Watergate scandal.

Along with the other Watergate burglars, G. Gordon Liddy and E. Howard Hunt, Barker was charged with, and pled guilty to, wiretapping, planting electronic surveillance equipment, and theft of documents. Barker was a paid CIA agent at the time of the break-in.

Barker also worked with CRP to get money into the Nixon campaign coffers off the books; it was via his bank account that twenty-five thousand dollars from Archer Daniels Midland Chief Executive Dwayne Andreas was obtained by CRP in violation of campaign finance laws.
