Rosen said he had a slight fever May 18, and decided to get tested for coronavirus.
Rosen immediately began to self-quarantine, and hopes to have another COVID-19 test on Thursday and get cleared.
"I appreciate everybody being so thoughtful and kind in sending well wishes. We will get past this. It is more important than ever to continue to wear a mask, wash your hands and socially distance," said Rosen.
