An adrift Democratic Party received a much-needed jolt of energy this week when Democratic senator Cory Booker took to the Senate floor to speak in protest of the Trump administration’s policies, vowing to hold it for as long as he was physically able.

To physically prepare for the feat, Booker used “a lot of tactics,” he said, including fasting and curbing water intake in the days before to make sure he could stand for so long and wouldn’t have to take a bathroom break.

New Jersey Sen. Cory Booker’s 25-hour speech on the Senate floor this week grabbed headlines around the world and garnered positive reactions from his fellow Democrats in Maryland and scrutiny from Republicans.
