Biden calls on Sen. 'Frank' Menendez

Vice President Biden might have had the late Sen. Frank Lautenberg (D-N.J.) on his mind Thursday at the swearing-in ceremony for former Newark Mayor Cory Booker (D).

The VP was overheard referring to another Garden State politician with a one-syllable first name, Sen. Robert Menendez (D), as “Frank” while Booker was being sworn into the Senate.

"Come on up here, Frank," Biden said to Menendez, before correcting himself, "Bob."

Just moments earlier, Biden noted that Senator-elect Booker won the vote to replace Lautenberg, who died in June at the age of 89.
