Controversy Rages Over Whether Trump's Impeachment Trial Is Constitutional Masood Farivar Three times in American history, the House of Representatives has impeached a president, and each time the Senate has voted to acquit him -- most recently a year ago when then-President Donald Trump was charged with seeking to pressure Ukraine's president into gathering political dirt against Trump's political rival, Democrat Joe Biden. Trump made history again this month, when he became the first president to be impeached a second time -- this time accused of instigating his supporters to storm the U.S. Capitol January 6 to prevent Congress from certifying Biden's election victory over Trump. The new impeachment charge of inciting an insurrection was approved by the House on January 13, a week before Trump left office. But with the Senate set to formally try the former president beginning on February 9, a constitutional controversy is swirling over whether the Senate can try and convict a former president. The question is not an academic one. On Wednesday, 45 of 50 Senate Republicans mounted an unsuccessful attempt to derail Trump's trial by questioning its constitutionality in a floor debate and roll call vote. Their reasoning: Once a president is out of office, he becomes a private citizen and cannot be tried and convicted even if he's already been impeached by the House. It is an argument that Trump's lawyers are expected to make while pressing for the former president's acquittal. "Private citizens don't get impeached," said Senator Rand Paul, a Kentucky Republican and a staunch supporter of Trump. "Impeachment is for removal from office, and the accused here has already left office." Yet the question of whether a former president can be tried remains unsettled and even those who dispute its constitutionality acknowledge there is room for debate. .
