One of the most prominent Republicans in the United States, Mitch McConnell, has supported the Trump campaign’s decision to look into “legal avenues” regarding allegations of electoral irregularities in the United States. “President Trump has a 100% right to review allegations of irregularities and weigh his legal options,” McConnell told the Senate on Monday local time. “Let’s not have lectures on how the president should immediately and cheerfully accept the results of the preliminary elections from the same people who have just spent four years refusing to accept the validity of the last election. Only a few Republicans have spoken out in support of President-elect Joe Biden’s victory, with most approving the president’s decision to challenge the result in court. Meanwhile, U.S. Attorney General William Barr has given prosecutors the green light to investigate allegations of voter fraud, but warned it was only to be substantive claims. “Since the voting in our current elections is now over, I authorize you to pursue substantial allegations of voting irregularities and vote tabulation prior to the certification of elections in your jurisdictions,” Barr said in a statement. . “Speculative, speculative, fanciful or far-fetched allegations should not be used as a basis for the opening of federal investigations.” It comes as the Trump campaign launches legal action in a number of key swing states – Nevada, Arizona, Georgia and Pennsylvania. .
