A staffer for US Senator Maria Cantwell has tested positive for coronavirus – the first known congressional worker to catch the virus, her office said Wednesday.

The unidentified patient, who works out of Cantwell’s Washington, DC, office, has had no known contact with the senator or other lawmakers, Cantwell’s office said in a statement.

The diagnosis led Cantwell to close her DC office for the remainder of the week. Remaining staffers will work remotely.

Cantwell, who represents Washington state, asked other staffers to get tested in light of the positive results.

Seven federal lawmakers since Sunday, including Sen. Ted Cruz, announced they are self-quarantining after coming into contact with people who tested positive for coronavirus.
