From Scout:

From Al Kamen at WaPo…..

Sen. Robert Menendez (D-N.J.), at the White House this spring for a meeting with other senators to discuss immigration with President Bush, was surprised when Bush approached him as the meeting broke up and observed: “Senator Martinez, you’ve been very quiet.”

“That’s Martinez,” Menendez said, pointing to Mel Martinez — Florida’s junior senator and Bush’s former secretary of housing and urban development.

“I’m Menendez.”

Bush turned bright red, we’re told. Seor Mayor?

The White House could not confirm the comment.
