A spokesperson for Senate Majority Leader Chuck Schumer, D-N.Y., said the upcoming prolonged absence of Sen. Ben Ray Luján, D-N.M., will not affect the Senate's schedule for confirming President Biden's pick to replace retiring Justice Stephen Breyer.

Luján, 49, suffered a stroke last week and remains hospitalized but is expected make a full recovery, his office announced Tuesday. Aides in Luján's office further explained that his recovery will keep him out of work from four to six weeks barring complications, according to The Hill.

"Sen. Luján's absence is not expected to affect the Senate’s timeline for moving a SCOTUS nominee," a spokesperson at Schumer's office said in a statement provided to Fox News Digital.

Luján's illness underscores the Democrats' fragile majority in the Senate. Republican Sens. Mitt Romney of Utah and John Hoeven of North Dakota are also absent after coming down with COVID-19, but they are expected to return to work next week.
