The lawyer for US President Donald Trump named Tanzania during a press conference on Thursday aimed at backing an unsubstantiated claim that the result from the 3 November election was fraudulent.

Joe Biden is the president-elect but Mr Trump has not yet conceded alleging voter fraud that favoured Mr Biden.

"Every state, almost every civilised country, even Tanzania, and places you wouldn’t think of, have rules about inspectors particularly for mail-in ballots," Rudy Guliani told journalists on Thursday.

Tanzania's President John Magufuli won a second term last month in an election that was marred with violence and claims of fraud.

Mr Giuliani used conspiracy theories and railed against the reporting of his team's legal challenges, saying the media had shown an "irrational pathological hatred for the president".
