(CNN) -- Moderate Democratic Sen. Joe Manchin of West Virginia has tested positive for Covid-19, he said in a tweet on Monday.

"This morning I tested positive for COVID-19," Manchin tweeted. "I am fully vaccinated and boosted and am experiencing mild symptoms. I will isolate and follow CDC guidelines as I continue to work remotely to serve West Virginians."

It's unclear what effect, if any, Manchin's isolation will have on Democrats' efforts to make progress on their legislative agenda. The Senate has a little under two weeks before it's scheduled to start its August recess, and Democrats have indicated hopes in passing bills -- from protecting same-sex marriage to increasing funding for semiconductor production in the US and changing laws surrounding prescription drug prices among other issues -- before leaving town for about a month.
