Speaking by telephone on ABC's "Good Morning America" on Thursday, Barr said Wednesday night's call was pretty exciting.
Barr said Trump congratulated her and talked about television and ratings. She said the Republican was happy for her. She says "I've known him for many years and he's done a lot of nice things for me over the years."
Barr has been a Trump supporter and plays a supporter on the updated sitcom.
"Roseanne" returned on Tuesday, more than two decades after the original ended its hit run. The hour-long debut episode was watched by 10 percent more viewers than saw the May 1997 finale of ABC's original "Roseanne."
