Feinstein said Reid told her there would be separate votes on two measures. One would be on her bill, including the bans on assault weapons and high-capacity magazines, the second just on prohibiting the magazines. Many Democrats think the ban on large-capacity magazines has a better chance of getting 60 votes than the assault weapons ban.
White House chief of staff Denis McDonough said Obama is not giving up on the assault weapons ban being added as an amendment.
"We're going to work on this," McDonough said in an appearance on CNN. "We're going to find the votes. It deserves a vote."
