Cardin’s office, after not commenting yesterday on what it called a “personnel matter,” said in a statement first provided to POLITICO on Saturday morning that “Aidan Maese-Czeropski is no longer employed by the U.S. Senate.”

“We will have no further comment on this personnel matter,” the statement added.

Maese-Czeropski on Friday night posted a statement to LinkedIn that did not unambiguously deny involvement.

“This has been a difficult time for me, as I have been attacked for who I love to pursue a political agenda,” he wrote. “While some of my actions in the past have shown poor judgement, I love my job and would never disrespect my workplace. Any attempts to characterize my actions otherwise are fabricated and I will be exploring what legal options are available to me in these matters.”

He separately denied allegations that he had accosted Rep. Max Miller (R-Ohio) in a Capitol hallway Wednesday by telling the Jewish lawmaker, “Free Palestine.”

Attempts to reach Maese-Czeropski on Saturday were not immediately successful. He had worked for Cardin since October 2021, according to congressional records, and previously worked as an intern for Sen. Dianne Feinstein (D-Calif.) in 2018.

U.S. Capitol Police did not respond to an email Saturday asking whether an investigation is underway. Aides to Senate Majority Leader Chuck Schumer and Minority Leader Mitch McConnell declined to comment.
