"My conduct was on point, and my personal emotion in all of this should be understood. I will fight against bigotry, racism, sexism, homophobia wherever I see it because I have benefitted from people speaking up in years past and I will do the same," Booker, a potential 2020 presidential candidate, told CNN's Jake Tapper.
The RNC sent an email Wednesday slamming Booker, 48, as “Derogatory Cory," and urging readers to picture a Republican male senator “mansplaining” to a female Cabinet secretary.
The committee concluded the email with the phrase "nevertheless, she persisted," which was adopted by feminist groups after Senate Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellHouse to act on debt ceiling next week White House warns GOP of serious consequences on debt ceiling Lindsey Graham: Police need 'to take a firm line' with Sept. 18 rally attendees MORE (R-Ky.) used it while justifying silencing Sen.

Booker disputed the charge that he had "mansplained."
