Sporting an unshaven beard and medical scrubs, Sen. Rand Paul is joining the effort to combat the coronavirus by volunteering at a hospital in his home state.

The Kentucky Republican, who was placed into quarantine after testing positive for the virus on March 22, said he is rested and ready to offer his services as a healthcare worker in his hometown of Bowling Green, Kentucky, during the crisis.

"I appreciate all the best wishes I have received," Paul, who is an ophthalmologist, tweeted on Tuesday. "I have been retested and I am negative. I have started volunteering at a local hospital to assist those in my community who are in need of medical help, including Coronavirus patients. Together we will overcome this!"

Paul was the third member of Congress and first senator to test positive for the disease and was criticized by some after it was revealed he had worked out in the Senate gym while awaiting test results. Paul said the insinuation that he went to the gym after being diagnosed as "completely false & irresponsible!" He later defended his decision not to self-quarantine between getting tested and receiving his results.
