[Video below.] Rudy Giuliani returned to the airwaves Wednesday night for the first time since being hospitalized earlier this month with viral pneumonia that reportedly left him in critical condition.

The 81-year-old former New York City mayor resumed hosting “The Rudy Giuliani Show,” opening the broadcast by telling listeners that his health had improved, although he acknowledged he is still recovering from the illness.

Giuliani had been hospitalized in Palm Beach, Florida, in early May, where reports indicated he was placed on a ventilator while doctors treated him for severe complications related to pneumonia.

News of his condition prompted widespread messages of support from political figures across the country and from both sides of the political aisle.

“I have to thank everyone who sent me prayers and good will,” he said. He specifically mentioned his gratitude to his family, the medical staff that tended to him and U.S. President Donald Trump, who Giuliani said called him after he became sick.

“It feels good to be back,” Giuliani said before cutting to his first break.

The longtime Republican politician has faced other serious health setbacks in recent years. Last September, Giuliani was hospitalized after a car accident in New Hampshire left him with a fractured vertebra and additional injuries.

Giuliani served two terms as mayor of New York City, with his leadership during the September 11 terrorist attacks in 2001 bringing him national prominence. After leaving City Hall, he launched an unsuccessful bid for the presidency in 2008 and later became a close adviser and personal attorney to President Trump.
