Hillary Clinton's campaign chairman says it has nothing more to say even as votes turn against her.
John Podesta told a crowd in New York early Wednesday that with states still uncalled "we're not going to have anything else to say tonight."
Clinton trails in the Electoral College count and Donald Trump is close to breaking the 270-vote threshold to become president.
Podesta told the crowd Clinton "has done an amazing job" and "is not done yet."

Some began leaving as the race wore on into the early hours of Wednesday morning.
Thousands had gathered at the Jacob K. Javits Convention Center in New York City for Clinton's election night party. The glass-ceilinged building was picked as a nod to what aides expected would be the historic election of the first female US president.
Clinton, her family and close aides have spent hours ensconced in a suite at the Peninsula New York, a luxury hotel in midtown Manhattan.
Donald Trump's campaign manager Kellyanne Conway, meanwhile, is describing the mood inside Trump Tower as "buoyant."
Podesta said: "It's been a long night, and it's been a long campaign, but we can wait a little longer, can't we?
He said the Clinton campaign "will have more to say tomorrow."
"Let's get those votes counted, and lets bring this home."
