Lamar Alexander, former senator and governor, condemns President Trump's January 6 actions in his new memoir as impeachable offenses, calling on Congress to assert its constitutional authority. The Tennessee Republican, who previously opposed witnesses in Trump's first impeachment trial, now believes Trump undermined the Constitution and assaulted peaceful power transition.

Alexander criticizes Republican senators for failing to check presidential authority, noting "the most disappointing difference between the first and second Trump terms was not what Trump did, but what the Senate majority did not do." He suggests bipartisan reading sessions to restore congressional prerogatives.

The former education secretary and presidential candidate expresses puzzlement that Republicans disdain his work on health research legislation that later enabled COVID vaccine development. Alexander urges current senators to follow their constitutional oath rather than remain compliant with presidential overreach.
