Story highlights Mook: Hillary apologized right away after that

Conway: I think she regretted getting caught

(CNN) Hillary Clinton campaign manager Robby Mook acknowledged the former secretary of state calling half of Donald Trump's supporters "deplorables" alienated voters, saying that's why the Democratic presidential nominee publicly expressed regret over the remarks so quickly thereafter.

"Hillary apologized right away after that and said that she misspoke and that she regretted the comment. That's something that Donald Trump wouldn't do, you know," he told CNN's Jake Tapper during a special edition of CNN's "State of the Union," filmed at Harvard University's Institute of Politics in Cambridge, Massachusetts. The event, "War Stories: Inside Campaign 2016," also included Trump's campaign manager Kellyanne Conway and was the first time that the two managers appeared together alone since the presidential campaign.

"I think it definitely could have alienated some voters and that's why she got out there right away," Mook added.
