Menendez steers clear of Lautenberg-Booker battle

Lautenberg, 88, has not yet announced his plans for 2014, and he said this week that Booker was “entitled to run.”

But he also suggested he would give Booker “a spanking.”

"I have four children, I love each one of them. I can't tell [you] that one of them wasn't occasionally disrespectful, so I gave them a spanking and everything was OK," Lautenberg told the Philadelphia Inquirer.

“This Week” host Martha Raddatz tried several times to get Menendez’s thoughts about Booker’s potential primary challenge, but Menendez wasn’t interested in discussing it.

“That’s a question for Sen. Lautenberg and Mayor Booker,” he said.
