Donald Trump for the first time left the door open to getting tested for coronavirus after interacting with several members of Congress who had contact with an infected person.

"I don't think it's a big deal. I would do it," he told reporters on Capitol Hill. "I feel extremely good. I feel very good. But I guess it's not a big deal to get tested, and it's something I would do."

But he did not commit to it after taking a limousine and Air Force One ride on Monday with Florida GOP Congressman Matt Gaetz, and shaking hands on Friday with Georgia GOP Congressman Doug Collins. Both are among several lawmakers in self-quarantine, despite claiming no virus symptoms, after interacting with the positive individual at a conservative policy conference that Mr Trump also attended.

The president made those remarks as he left a meeting about the coronavirus outbreak with Senate Republicans. He made the rare trip to the Capitol to try and rally his fellow Republicans around an economic stimulus plan his staff is still cobbling that they say is needed to ward off a major slowdown amid coronavirus fears.

As he headed back to the White House, he again downplayed the threat from the sickness: "It will go away. Just stay calm."

He did not explain why he thinks so, but in recent weeks has said he expects as temperatures warm, the virus will be killed. Some public health experts disagree, however.

Democrats and some former public health officials have criticised Mr Trump for being too dismissive of the virus, saying his administration's response was too slow, causing, among other things, a delay in the production of testing kits.
