Senate Majority Leader Harry Reid’s (D-Nev.) wife, Landra Reid, remained in serious condition Friday following a car crash Thursday that left both Landra Reid and the couple’s daughter, Lana Reid Barringer, injured.

Reid, who spent much of the night at his wife’s bedside at Inova Fairfax Hospital in Falls Church, Va., returned to the hospital Friday to be with her, Reid spokesman Jon Summers said.

“Mrs. Reid remains in serious condition. Lana was released last night. Sen. Reid and Landra’s family is coming to be by her side. Sen. Reid was at the hospital until almost midnight last night. He stayed there until the doctors told him he needed to leave so his wife could get some sleep. He returned first thing this morning to be with her and is still there.”

Landra Reid, who is 69 years old, suffered a broken back and neck, among other injuries, and while she has feeling in her extremities it remains unclear how long she will be hospitalized.

The four-car accident along Interstate 95 in suburban Virginia came just a week after Reid filed for re-election in his home state of Nevada, where he is facing an uphill battle.

What, if any, effect the accident will have on Reid’s travel and fundraising schedule remains unclear, and Summers said the welfare of his wife is Reid’s sole concern at the moment.

“His wife is his primary focus right now. That’s the love of his life,” Summers said Friday.
