According to foreignmeida reports a top member of US President Donald Trump's Republican Party, Senate Majority Leader Mitch McConnell, has congratulated Joe Biden on winning the presidential election last month.

Senator McConnell spoke after the electoral college formally confirmed Biden's victory over Trump.

The Democrat won 306 electoral college votes to Trump's 232.

President Trump still refuses to concede, making claims of widespread fraud.

Relations with the Senate, currently controlled by the Republicans, is supposed to be crucial to Biden's presidency

He visited several states to campaign for the Democrats in next month's Senate run-off elections. Two seats will be decided on 5 January and could determine whether or not his party takes control of the chamber. Democrats already control the House of Representatives.

After Monday's confirmation, three world leaders who refused to congratulate the president-elect , Russia's Vladimir Putin, Brazil's Jair Bolsonaro and Mexico's Andrés Manuel López Obrador, did so on Tuesday.

President Trump does not appear to be changing his stance. Tweeting on Tuesday, that "tremendous evidence" of voter fraud was "pouring in".
