Democratic Senator Chris Murphy was hospitalised on Saturday after suffering a stroke while watching his son's ice hockey game, his office confirmed on Sunday.

The Connecticut senator began experiencing sudden numbness in his arm during the match, his chief of staff, Allison Herwitt, said in a statement.

He was taken to a local hospital, where doctors found he had suffered a stroke, and was then transferred to Johns Hopkins Hospital in Baltimore for monitoring. 'The doctors are encouraged by his progress, he is awake and alert, and we are optimistic he will make a full recovery,' Herwitt said. She added that he was 'responding well to treatment'.

Murphy's office has not said what type of stroke he suffered or how severe it was. It has also not said when he might leave hospital or return to the Senate. No further medical details have been released.

Chris Murphy Was Campaigning Ahead of the Midterm Elections

Murphy, one of the Senate's most visible Democrats, had been travelling the country campaigning for his party ahead of Tuesday's midterm elections. He is not on the ballot himself. He is widely seen as a potential contender for the 2028 presidential nomination.

President Donald Trump, a frequent target of Murphy's criticism, told reporters on Sunday he was surprised by the news and would contact the senator 'at the right time'. 'Certainly we don't like to hear a thing like that,' he said.

Senator John Fetterman of Pennsylvania, who suffered a near-fatal stroke during his 2022 Senate campaign, said he understood 'all too well how much this impacts your life'.

He wrote on X that his family was 'rooting for Chris and his family for a full and speedy recovery'. Republican senators including Chuck Grassley of Iowa and Pete Ricketts of Nebraska also offered prayers.

Chris Murphy's Career as a Gun Reform Advocate

Murphy was first elected to the House of Representatives in 2006 and moved to the Senate in 2012, serving six years in the lower chamber. His Senate election came weeks before the Sandy Hook Elementary School shooting in his home state, after which he became one of Congress's most prominent advocates for stricter gun laws.

In 2016 he held the Senate floor for almost 15 hours to demand tougher background checks. He has also been a vocal critic of Mr Trump.

Chris Murphy's Stroke Follows Other Senate Health Emergencies

Murphy is one of several sitting senators to have suffered a stroke in recent years. Senator Chris Van Hollen of Maryland said in May 2022 that he had suffered a minor stroke, and Senator Ben Ray Luján of New Mexico was hospitalised after a stroke earlier the same year. Luján returned to the Senate in March after his recovery.

Sudden numbness or weakness in the face, arm or leg, particularly on one side of the body, is a recognised warning sign of stroke. In the UK, the NHS uses the FAST test, face drooping, arm weakness, speech difficulties and time to call 999, to help people spot a stroke. Prompt treatment can limit damage to the brain.
