Sen. Chris Murphy, a Connecticut Democrat, was hospitalized this weekend after suffering a stroke, his office announced Sunday. The 53-year-old is undergoing monitoring at Johns Hopkins Hospital and responding well to treatment.

Murphy began experiencing numbness in his arm Saturday afternoon while attending his son's hockey game, according to a statement from his chief of staff, Allison Herwitt. He was taken to a local hospital where doctors determined he had suffered a stroke, then transferred to Johns Hopkins. Herwitt said Murphy is expected to make a full recovery.

Murphy, a foreign policy voice within the Democratic caucus, had just returned from a multistop tour across the Middle East. Before his hospitalization, he publicly warned that President Trump would significantly escalate military actions against Iran after the midterm election.

Murphy's hospitalization is the latest medical crisis to affect Congress this year. Sen. Mitch McConnell, a Kentucky Republican, missed several months of Senate duties due to an extensive hospital stay and rehabilitation. Rep. Tom Kean, a New Jersey Republican, was absent from the Capitol for months undergoing treatment for depression.

In 2022, three prominent lawmakers experienced strokes: Sen. Ben Ray Lujan of New Mexico, Sen. Chris Van Hollen of Maryland, and then-Senate candidate John Fetterman.
