Sen. Joe Manchin, D-W.V., said Monday that he has tested positive for COVID-19. The news comes as Democrats seek to advance legislation before the August recess.

While President Joe Biden has worked in a limited capacity this week while having COVID-19, Manchin would not be able to remotely cast votes in the Senate. The conservative Democrat is considered a key swing vote.

Sen. Lisa Murkowski, R-Alaska, also tested positive for COVID-19. She said she experienced flu-like symptoms.

In a tweet, Manchin indicated that his symptoms were mild and that he will continue to work remotely until Congress enters the August recess.

While the House enacted legislation during the pandemic that created a proxy voting system for remote voting on legislation, the Senate did not enact similar legislation.

Manchin’s contracting COVID-19 could help or hinder the passing of Democrat legislation.

He has been a roadblock to the Biden agenda. The long-time senator recently prevented the passing of the Women’s Health Protection Act as well as key climate change legislation and the Build Back Better plan.

Manchin's absence coincides with Sen. Patrick Leahy, D-Vt., who is recovering from a fall, as well as Sen. Tom Carper, D-Del., who tested positive for COVID-19 last week.
