Former U.S. Rep. Ron Paul was hospitalized on September 25 after his speech slurred during a livestream video.

The former Texas congressman appeared to be having a stroke-like event while talking about economics in a video posted to his YouTube channel. Within seconds, Paul’s voice was completely mumbled and unidentifiable.

Later in the day, Paul updated his fans and colleagues about his condition via Twitter. He was hospitalized for “precautionary reasons.”

“Message from Ron Paul: I am doing fine. Thank you for your concern,” read his tweet followed with a picture of himself from his hospital bed.

Paul’s son, Sen. Rand Paul (R-Kentucky), also took to Twitter to thank the public for their prayers for his dad’s well being.

“Thank God, Dad is doing well. Thank you for all your prayers today,” said Paul.

Sen. Ted Cruz (R-Texas) expressed his relief for Paul’s health following the tweet.

“Praise God. Millions of prayers being lifted up for @RonPaul,” said Cruz.

Paul ran for president three times in the past as the Libertarian nominee in 1988. Later, he ran unsuccessfully for the Republican nomination in 2008 and 2012. Paul also served as a flight surgeon in the U.S. Air Force from 1963 to 1968.
