GRAND RAPIDS, MICHIGAN (REUTERS) - US President-elect Donald Trump told supporters in Grand Rapids, Michigan, that there is no longer any need to prosecute his Democratic challenger Hillary Clinton.

Mr Trump stopped in Grand Rapids to thank traditionally Democratic Michigan voters for giving him the state's 16 electoral votes in the US presidential election.

During the campaign, Mr Trump had frequently accused Mrs Clinton of endangering US national security by using a private e-mail server when she was secretary of state, and said she should be jailed for her actions.

But when supporters on Friday (Dec 9) began calling for Mrs Clinton's prosecution, he dismissed the idea.

He told the group: "That plays great before the election, now we don't care."

The FBI investigated Mrs Clinton and called her actions "extremely careless", but said they would not be filing criminal charges against her.
