WASHINGTON -- Sen. Al Franken said Monday he will not sit in the chamber during Israeli Prime Minister Benjamin Netanyahu's speech to Congress Tuesday, while his Democratic colleague Sen. Amy Klobuchar said she will be there.

In an e-mail, Franken said the speech had "unfortunately become a partisan spectacle."

The Israeli prime minister, amid his own re-election campaign,accepted an invitation by GOP House Speaker John Boehner and Senate Majority Leader Mitch McConnell to address a joint session of the Republican-led Congress. The two Republican leaders did not check with the White House or the State Department -- considered a breach of protocol.

Netanyahu is expected to talk about his opposition to talks the United States is having with Iran about its nuclear program. Obama is not expected to meet with Netanyahu when he is in town.

"I'd be uncomfortable being part of an event that I don't believe should be happening," said Franken. "I'm confident that, once this episode is over, we can reaffirm our strong tradition of bipartisan support for Israel."

Franken joins Democratic Reps. Betty McCollum and Keith Ellison, who said earlier this month they would boycott the speech.

Republican Reps. Tom Emmer, John Kline and Erik Paulsen said they will be there, as will Democrat Reps. Rick Nolan, Tim Walz and Collin Peterson.
