PHILADELPHIA (AP) — Bernie Sanders’ delegates are waiting to see whether the Vermont senator frees them to vote for Hillary Clinton in Tuesday’s roll call.

Nebraska delegate Jeff Leanna says the topic was a top discussion item at a breakfast meeting involving his state, Colorado and Nevada. He says regional members of the Clinton campaign were reaching out to some delegates to see if they would be willing to switch. Leanna says he’s willing to cross over if Sanders agrees to release them during a private meeting with delegates Monday.

Louise Edington of Utah says most in her delegation also were discussing but not revealing what they might do. Sanders won that state with nearly 80 percent of the vote.

Sanders won 1,846 pledged delegates from primaries and caucuses.
