Sen. Chris Murphy remained hospitalized Tuesday after suffering a stroke over the weekend, his office confirmed.
"He's continuing to improve and heartened by the outpouring of well wishes," Josh Sorbe, Murphy's communications director, told CNBC in an emailed statement. "He early voted in Connecticut, and he encourages everyone to make their voices heard today by voting and sending a message in this defining election."
His office did not offer additional details when asked about his status or his expected recovery.
The Senate is due back in session Monday following Tuesday's midterm elections.
Murphy began experiencing stroke symptoms on Saturday while at his son's hockey game, his chief of staff Allison Herwitt said in a statement Sunday.
