Hillary Clinton's campaign is backing efforts to push for vote recounts in several key states.

Green Party candidate Jill Stein has already raised millions of dollars to have another look at votes in Wisconsin.

Donald Trump has sent a string of tweets this morning citing Mrs Clinton's earlier comments about respecting democracy. The President-elect says the results should be respected , instead of being challenged and abused.

Hillary Clinton conceded the election when she called me just prior to the victory speech and after the results were in. Nothing will change

Juliet Eilperin, The Washington Post's White House bureau chief, told Rachel Smalley Mr Trump won by 107,000 across Michigan, Wisconsin and Pennsylvania.

"It is highly unlikely that there would have been sufficient tampering to alter the outcome in all three of the states, which is what would be needed."

But former Democratic candidate Bernie Sanders said there's nothing wrong with counting votes again.

"That's a legal right, they do it. I don't think that Hillary Clinton, who got two million more votes than Mr Trump in the popular election, thinks that it's going to transform the election. But do people have the legal right to do it? Yeah, we do."
