Arizona Congressman Paul Gosar says he has quarantined himself at home after he came in contact with a person infected with the new coronavirus at a national conservative politics conference in the Washington, D.C., area.

The Republican Gosar says he and some of his staff members came in contact with an individual who has since tested positive for and hospitalized for COVID-19. Gosar says he and staff members came in contact with the person while attending the annual Conservative Political Action Committee conference in Maryland last month. Gosar says he was with the unidentified individual for an extended period of time and he says the two shook hands several times. Gosar says neither he nor his staff feel ill.

Gosar’s office will be closed this week while he and staff are under quarantine.

Texas Senator Ted Cruz says he’s also decided to quarantine himself after coming in contact with a person who has tested positive for Covid-19 at the same conference in Maryland.
