Nov 21 (Reuters) - A federal judge on Saturday dismissed a lawsuit filed by President Donald Trump's campaign that sought to throw out millions of mail-in votes in Pennsylvania, dealing a major blow to Trump's flailing efforts to overturn his Nov. 3 election loss to Democratic President-elect Joe Biden.
U.S. District Judge Matthew Brann in Williamsport, Pennsylvania, described the case as "strained legal arguments without merit and speculative accusations."
Brann added that he "has no authority to take away the right to vote of even a single person, let alone millions of citizens."
