But new audio obtained by CNN shows a senior Sanders aide -- on the eve of the Nevada convention -- encouraging the senator's supporters try to "take over" the convention, change party rules and continue the "revolution" that Sanders has long campaigned on.
"You should not leave," Joan Kato, the national delegates director, told Sanders supporters in a meeting last week at the Rumor Boutique Hotel. "I'm going to repeat that, unless you are told by someone from the campaign ... that you can leave, you should not leave."

Hillary Clinton’s campaign is trying to seize on the turmoil Donald J. Trump’s ascent has caused within the Republican Party, hoping to gain the support of Republican voters and party leaders including former elected officials and retired generals disillusioned by their party’s standard-bearer.

More broadly, Mrs. Clinton’s campaign is repositioning itself, after a year of emphasizing liberal positions and focusing largely on minority voters, to also appeal to independent and Republican-leaning white voters turned off by Mr. Trump.

But her campaign, confident that the young people and liberals backing Senator Bernie Sanders of Vermont will come around to support Mrs. Clinton in November, is focusing its efforts on white working-class women and suburban women who tend to vote for Republican presidential candidates, but who polls show hold negative views of Mr. Trump.
