There has been an outpouring of support and condolences for Gary Sinise in response to the actor's announcement that his son, McCanna Anthony "Mac" Sinise, passed away last month at age 33 after a years-long cancer battle.

In a tribute, Sinise explained that Mac, had worked to create beautiful music while facing cancer. "Mac's inspiring parting gift to us," Sinise wrote.

Sinise's post on X linking to the tribute has amassed nearly three million views so far.

"What a beautiful tribute, my friend. Though I never knew him, it is obvious that Mac was blessed with your strength and integrity. What a special young man. My deepest condolences to you and your family," actor Lou Diamond Phillips said in a post on X.

Actress Patricia Heaton urged people to reach out to Sinise, tweeting, "Friends, please reach out to my pal Gary, who recently lost his only son Mac to cancer. Mac put up a valiant fight, with the help of his devoted family and teams of dedicated doctors who did their best. This is a very special family, who give so much to the world, but now is the moment to give back some of that love. #RIPMacSinise"

Actor James Woods tweeted, "People call each other 'brother,' but I don't believe in that. If I did, however, Gary Sinise would be the man I would say it to. His loss is beyond words, but my heart is full of him today. May God bless him and his family in this terrible time. #RIPMcCannaSinise."

"RIP. God bless y'all," GOP Rep. Chip Roy of Texas tweeted.

Former Arkansas Gov. Mike Huckabee, who is the father of current Arkansas Gov. Sarah Huckabee Sanders, tweeted, "Not a finer person on earth than @GarySinise & sincere condolences to him and his family."
