Kansas Rep. Jake LaTurner tested positive for COVID-19 while participating in a joint session of Congress that certified President-elect Joe Biden’s victory in the Electoral College.

LaTurner’s office tweeted early Thursday that the freshman Republican “is not experiencing any symptoms at this time.” LaTurner had voted to object to the counting of Arizona’s electoral votes for Biden, but his tweet said he was following the advice of the House physician and federal Centers for Disease Control guidelines and not returning to the House floor for other votes.

LaTurner’s tweet said he took his COVID-19 test “as part of Washington DC’s travel guidelines that requires visitors be tested,” without providing additional details.

LaTurner took office Sunday, representing the 2nd District of eastern Kansas. He is a former Kansas state treasurer and unseated GOP Rep. Steve Watkins in the August primary.
