In an email titled “Derogatory Cory,” the RNC urged readers to “picture” a male Republican lawmaker “mansplaining” to a female Cabinet secretary.

“There’d be so many triggered Democrats that there’d be a hashtag within minutes, campus protests across the country, and the topic-du-jour for celebrities at Hollywood’s next award show,” the email reads. “But because the party affiliations were reversed, Derogatory Cory got nothing but praise from the selectively-outraged base he was clearly performing for yesterday.”

The email comes after Booker on Tuesday criticized Nielsen during an open hearing for claiming she did not hear President TrumpDonald John TrumpAccuser says Trump should be afraid of the truth Woman behind pro-Trump Facebook page denies being influenced by Russians Shulkin says he has White House approval to root out 'subversion' at VA MORE use the phrase “shithole countries” to refer to some African nations, El Salvador and Haiti during a meeting on immigration.

"When ignorance and bigotry is allied with power, it is a dangerous force in our country. Your silence and your amnesia is complicity," Booker told Nielsen. 

Booker on Wednesday called Trump’s reported comments about immigrants “gut-churning,” blasting the president for what he described as bigotry. 

"It's not the vulgarity. It's definitely not the vulgarity,” Booker told CNN. “It's the bigotry and the discrimination that comes from the mouth of the president that, in our climate today, causes damage.”
