U.S. Sen. Rand Paul of Kentucky reportedly passed the time Wednesday during President Donald Trump's impeachment trial by working on a crossword puzzle.

ABC News reported that several senators broke or bent the Senate rules and brought Apple watches into the chamber, played games and caught up on emails.

The Associated Press reported that "A Democrat in the back row leaned on his right arm, covered his eyes and stayed that way for nearly a half-hour" and "Some openly snickered when lead prosecutor Adam Schiff said he’d only speak for 10 minutes. And when one of the freshman House prosecutors stood to speak, many of the senator-jurors bolted for the cloak rooms, where their phones are stored."

Sen. Elizabeth Warren, a Democratic presidential candidate, was reportedly playing a game on paper during the proceedings, according to ABC. Other senators were seen reading non-impeachment materials and emails.

And Paul, ABC reported, used the time to work on a crossword puzzle and even a paper airplane.

A Paul spokesman told ABC that "all smart people do crossword puzzles" when asked for comment Wednesday. His office did not respond to a phone call and email from The Courier Journal seeking comment Thursday.

Paul has been critical of the impeachment proceedings from the beginning, calling the ordeal a "partisan charade" and "hyper-partisan."

Trump faces two articles charging him with abuse of power and obstruction of Congress. He's accused of soliciting foreign interference in the 2020 election by pressuring the president of Ukraine to promise to investigate former Vice President Joe Biden, a 2020 Democratic presidential candidate, and his son, Hunter Biden.

Paul has previously said he wants to call Hunter Biden if witnesses are called in the case. Hunter Biden's seat on Burisma Holdings' board prompted allegations that Joe Biden used his position to protect the company against an anti-corruption probe.
