Democratic Leader Frank Dermody told CNN he and other Democrats found out about Lewis' positive test Wednesday -- after Lewis said he had finished his self-isolation and announced his diagnosis publicly.

In a Facebook Live video, Lewis claimed he wore a mask that day, did not shake any hands, and that he only interacted with about five people.

The Dauphin County lawmaker said he notified "the House of Representatives and our caucus Human Resources department" of his diagnosis and they worked to determine who he may have been in contact with and may have possibly exposed to the virus.

"Anyone I had contact with that day were notified, they were able to quarantine, get tested, no positive tests that I'm aware of," Lewis said on Facebook.

Lewis said he chose to keep his positive case private "out of respect for my family, and those who I may have exposed."

"Now that I have fully recovered and completed the quarantine as required by the Department of Health, I feel now is the appropriate time to share this information with the public and my constituents," Lewis said Wednesday.

CNN has reached out to Lewis' office.

Dermody said in a statement that "while we are pleased to learn that this House member seems to have recovered, it is simply unacceptable that some House Republicans knew about this for more than a week and sat on that knowledge."

"Knowing how House members and staff work closely together at the Capitol, we should have been made aware of this much sooner," Dermody said.

Dermody told CNN that he was "angry and disappointed" when he found out about Lewis' test on Wednesday afternoon from a local news report, prompting him to call the Republican leadership and House chief clerk to see if was true.

"We're talking to (Republicans).

On Twitter, Diamond said he did not get tested.

He wrote that he was notified on May 21 he had come in contact with someone on May 14 who tested positive for Covid-19, but he was not informed of who that individual was.

Lewis was only in the Capitol for a short period of time within that window -- so tracing who he was in contact with was easily verified, and as he said in his statement, anyone who needed to be notified was notified and is currently self-isolating," he added.

As coronavirus cases began to rise in the state, the Pennsylvania House passed a temporary rule in March allowing its 203 members to vote remotely or by proxy.
