Ms. Gilbert, who will return playing Roseanne’s daughter Darlene and is an executive producer of the series, said the show sought to talk about the political divide “within the context of a family.”
Ms. Barr’s real-life support of the president and her frequently charged opinions that she shares on Twitter have already prompted a BoycottRoseanne hashtag on social media.
Ms. Barr said that her children took away her Twitter account, and that she planned to stay off social media in the coming months.
“I didn’t want it to overshadow the show,” she said.
She added, using a neologism found on the internet, “I think it’s the time to close ranks and see an end to ‘hatriotism’ in this country.”
“Roseanne” is just the latest reboot in television in the last few years. Shows including “Full House,” “24” and “The X-Files” have also been brought back as TV executives, particularly on the broadcast networks, try to grab the attention of viewers who have never been more distracted.
ABC needs a couple of hits. Despite introducing the biggest new hit in TV this season — its Monday night drama “The Good Doctor” — the network is in last place among the 18-to-49-year-old demographic important to advertisers. Shonda Rhimes, its most reliable hitmaker, jumped ship and signed a deal to make all her future projects for Netflix.
ABC will not rest its hopes entirely on “Roseanne.” It is also bringing back “American Idol” in March, a show that went off the air on Fox two years ago because of low ratings.
Though “American Idol” lost a big part of its audience, Ryan Seacrest, who will return as host, said on Monday that the show would largely remain the same. “To change the show drastically,” he said, would be a mistake.
The judges of the new show will feature Katy Perry, Luke Bryan and Lionel Richie.
And will there be a new Simon Cowell to play bad cop on the show? Don’t bet on it.
“No one is here to say anything negative,” Ms. Perry said.
