Sen. Chris Murphy was hospitalized after suffering a stroke on Saturday, but his office said he is awake, alert, responding well to treatment and expected to make a full recovery.

Murphy first noticed numbness in his arm at his son’s hockey game and was taken to a local hospital before being transferred to Johns Hopkins for monitoring, chief of staff Allison Herwitt said.

His office has not disclosed the type of stroke, the treatment he received or when he might be discharged.

The hospitalization came amid Murphy’s campaigning for Democratic candidates in Connecticut and several swing states; he was scheduled to campaign in New Hampshire on Sunday, though it is unclear whether that appearance was canceled.

Gov. Ned Lamont and Connecticut Lt. Gov. Susan Bysiewicz shared messages of support, with Bysiewicz saying she had recently seen Murphy energetically encouraging voters.

Dr. Paul Wright of Hartford HealthCare said sudden arm numbness, vision loss, slurred speech, difficulty understanding speech or double vision may signal a stroke and warrant immediate medical attention.

Wright said prompt treatment can improve outcomes and recommended managing risk factors such as high blood pressure, elevated cholesterol and smoking; he also urged annual physical exams to catch potential concerns early.

Strokes can affect younger people, too, and may be associated with genetic conditions, irregular heartbeats or tears in arteries.

Murphy has served in the Senate since 2013, after being elected to the House in 2006, and is known for his work on gun control and immigration; he was not up for reelection in the 2026 midterms.

At 53, Murphy is a prominent Democratic campaign surrogate and foreign policy voice who has been viewed as a possible 2028 presidential contender.

After touring the Middle East in October, Murphy criticized the U.S.-Israel war on Iran and pledged that Democrats would withhold its funding if they won the Senate; he also said he would investigate Trump and his family over alleged corruption.

Murphy became a prominent advocate for tighter gun laws after the 2012 shooting at Sandy Hook Elementary School in Newtown, Connecticut.
