There is one person on Capitol Hill for whom Garry Shandling’s death hits especially close to home: Al Franken.

Franken, the comedian-turned-senator known for his bits on Saturday Night Live, paid tribute to Shandling on Facebook after the 66-year-old comic died in Los Angeles on Thursday.

“I am shocked and saddened by Garry Shandling’s death,” Sen. Franken (D-Minn.) wrote in a post that has received 4,600 reactions so far.

“Garry was a great friend, a hilarious comedian, and a brilliant writer, whose influence on comedy is impossible to overstate. He brought a deep, unflinching understanding of human nature to his work and to his friendships. He will be missed by so many friends whose lives he enriched in so many ways. I cannot believe I won’t see him again. Yesterday was a very sad day for those of us who loved him. Thank you, Garry, for all you gave us. Rest in peace.”

Shandling has been described as one of the most influential comics of his generation. In the wake of his death, fans are retweeting his posts on Twitter, where he communicated with friends and told jokes.
