“I haven’t seen them,” Fischer said of the emails.

Reps. Jeff Fortenberry and Adrian Smith also said they hadn’t seen anything on the emails.

Sen. Ben Sasse didn’t respond to a request for comment. Nor did Dan Welch, the chairman of the Nebraska Republican Party, which has received Ricketts donations as well.

Rep. Don Bacon said he had only read a news article about the controversy.

“I appreciate the fact that he apologized,” Bacon said. “I really don’t have anything more to add other than that. I think he apologized and tried to make it right.”

Kara Eastman, a Democrat who ran against Bacon last year and hopes for a rematch in 2020, challenged Bacon to return the donations his campaign received from Ricketts — $2,700 in 2016 and another $2,700 in September.

Eastman said in a press release last week that she was “sickened beyond words” at the emails.
