A US congressman announced that he tested positive for coronavirus hours after giving an address to fellow lawmakers on the floor of the US House of Representatives in Washington.

South Carolina Republican Joe Wilson spoke on Wednesday to praise President Donald Trump for his role in the Pfizer-BioNTech vaccine rollout, which began this week.

“The life-saving Covid-19 vaccine that he promised to deliver has arrived in record time. Hallelujah,” he said.

He later said in a statement that he would be quarantining over Christmas. "Thankfully I feel fine and do not have any symptoms," he said. "It is so important that we all do our part to help prevent the spread of this virus."

US Interior Secretary David Bernhardt - who oversees US national parks and federal lands - also tested positive on Wednesday. He was tested before a cabinet meeting with President Trump, and did not attend the meeting as a result of his infection.

Secretary of State Mike Pompeo also skipped the meeting. He is currently isolating after he was exposed to someone who was infected.
