Donald and Melania Trump have gone on Twitter to express their outrage over the results of the US presidential election.

“Since when does the Lamestream Media call who our next president will be? We have all learned a lot in the last two weeks!” the incumbent President wrote.

“The American people deserve fair elections. Every legal—not illegal—vote should be counted. We must protect our democracy with complete transparency,” the First Lady commented.

US media have reported on Joe Biden's victory in the US presidential election. Although the election process is not over yet, some world leaders have already congratulated Biden on his victory.
