The former "Desperate Housewives" star reported to the Federal Correctional Institution in Dublin, California on Tuesday, October 15 after she was sentenced to 14 days for her involvement in the U.S. college admissions scandal.
"I don't think anyone involved in the college fraud cases should go to prison," he tweeted. "That includes past cases as well. Community service, fines, yes. But prison time, no. My heart goes out to Felicity, Bill Macy and their family."
Huffman pleaded guilty to paying disgraced admissions consultant Rick Singer to help her doctor her 19-year-old daughter Sophia's test results in an effort to get her into an elite college.
Upon her release later this month, Felicity will face 250 hours of community service and a year of supervised release.
She is expected to serve 13 days of her 14-day sentence.
