WASHINGTON — White House Press Secretary Sarah Huckabee Sanders refused to weigh in on the cancellation of Roseanne Barr’s ABC show, after the Trump-supporting comedian dashed off a racist tweet.

“The president is focused on North Korea, he’s focused on trade deals,” Huckabee Sanders replied aboard Air Force One Tuesday when asked for President Trump’s thoughts on the controversy.

Asked directly if Barr’s popular sitcom should have been pulled by the network, the press secretary dodged again. “That’s not what the president’s looking at,” she said. “We have a lot bigger thing going on in the country right now.”

Trump also did not answer shouted questions from The Post about the show’s demise when he left the White House for Nashville, where he was to appear at a campaign rally.

In the past, though, the president has taken time for Barr.

He called the comedian in March to congratulate her for the ratings of her rebooted show.

At a rally in Ohio the same month, Trump gushed about the comedian and the show. “Look at Roseanne, look at her ratings,” the president said. “They were unbelievable. Over 18 million people. And it was about us.”

The president added that the mainstream media hasn’t “figured it out yet.”

“He’s just happy for me,” Barr said in March about her call with the president. “I’ve known him for many years and he’s done a lot of nice things for me.”

During the 2016 campaign cycle, Barr was one of the president’s few celebrity supporters.
