Trump seals Republican nomination

Mr Trump's adult children led the New York delegation at the convention

Donald Trump has officially clinched the Republican nomination for US president as speakers hammered Democrat Hillary Clinton on day two of the Republican National Convention.

Mr Trump is expected to accept the nomination on Thursday after state delegates formally selected him.

The theme of Tuesday in Cleveland was "Make America Work Again".

However, the speakers focused almost exclusively on attacking Mrs Clinton, the likely Democratic nominee.

New Jersey Governor Chris Christie, a former prosecutor, held a mock trial for Mrs Clinton as the crowd chanted "lock her up".

Mr Christie and others criticised Mrs Clinton's use of a private email account while she was serving as secretary of state.

An FBI investigation said she was "extremely careless" but found her actions didn't warrant criminal prosecution.

The crowd repeatedly chanted "lock her up!"

But Mr Christie and and the crowd disagreed as Mr Christie repeatedly yelled "guilty".

He said she has "selfish, awful judgement" and was to blame for various foreign policy problems in Libya, Syria and elsewhere.

Mr Trump's children also played a prominent role on Tuesday, standing with the New York delegation as he was declared winner and delivering remarks.
