WASHINGTON — President Donald Trump on Wednesday asked the U.S. Supreme Court to let him join a long-shot lawsuit by Texas seeking to overturn his election loss by throwing out the voting results in four states, litigation that also drew support from 17 other states. In a court filing, Trump asked to intervene in the Texas lawsuit, the latest litigation to try to undo Democratic President-elect Joe Biden’s victory over the Republican incumbent in the Nov. 3 election. In a separate brief, lawyers for 17 states led by Missouri’s Republican Attorney General Eric Schmitt also urged the nine justices to hear the case.
