Franken, speaking during a press event in Rochester, said he supports limits on ammunition magazines to 10 rounds and tightening the nation’s system of background checks. But, he declined to say whether he supported a ban on assault weapons, a key provision of the president’s plan.

“I guess I don’t have an answer for you,” said Franken spokesman Marc Kimball, following a press conference during which the senator omitted a ban on assault weapons when asked about gun restrictions he might support.

“He’s been listening to Minnesota, trying to be thoughtful on this and trying to get input from people from a wide spectrum of views,” Kimball added.
