David Brock, founder of the pro-Clinton super PAC Correct the Record, stated that “everything’s fair game” while discussing Vice President Joe Biden and that as the campaign goes on Hillary Clinton might “there are going to be some issues where…maybe she even comes out and says something that is in disagreement with what she said a few years ago” on Wednesday’s broadcast of MSNBC’s “All In with Chris Hayes.”

Brock said a report in New York Magazine that Correct the Record is leading an effort to gather opposition research on Vice President Joe Biden, “was an anonymous report. I don’t really want to sit here, this is a pro-Hillary Clinton super PAC, but I don’t want to sit here and talk about our internal strategies, you can understand that. … The thing I really don’t like are Democratic strategists who go out into the media and reveal what they’re doing. So, I don’t want to do that.”

When asked if he thought there was “an increasingly damaging narrative about the vice president, that perhaps there was political calculation in involving Beau Biden in the narrative about his bid for the presidency?” Brock answered, “the truth is, all politicians calculate, and so, I mean, that’s just the truth.”

When asked if such a narrative is “fair game,” Brock answered, “I think everything’s fair game.”

He further denied that he knew anything about Politico’s story that Biden leaked his son’s dying wish that the vice president run for president.

Regarding Clinton’s stance on the TPP, Brock stated, “I think as the campaign goes on, there are going to be some issues where maybe she hadn’t taken a stand before, and maybe she even comes out and says something that is in disagreement with what she said a few years ago. I mean, that’s all going to be possible in a campaign, sure. So, she evaluated this issue. She took her time. She came up with a decision that I think will show her to be, what I believe is the real progressive champion in the race.”

After being asked, “maybe upwards of 40, 45 comments in support of the TPP, I mean, you don’t think that that’s an issue at all?” Brock responded, “No, I really don’t. No. I mean, people now know where she stands, and that’s what she’s going to do as a presidential candidate and hopefully, if president.”
