Sen. Amy Klobuchar, D-Minn., said Tuesday she is not surprised new Attorney General Bill Barr is not recusing himself from special counsel Robert Mueller's investigation, but she does not think he is making the right decision.

"I thought he should have recused himself," the presidential candidate told MSNBC's "Andrea Mitchell Reports." "I was very concerned, given what he said in that memo about a president and what a president can do and whether a president can basically make the laws, so that really bothered me."

Barr said during his confirmation hearing he respected Mueller, Klobuchar said, and he will do all he can to release his report.

"There is every reason that he should put the public's interest in mind," Klobuchar said. "We saw what Russia did last time. We know from intelligence officials that the Trump administration, what they may do again. And for the sake of our democracy and our country, he must make this report public."

She also spoke about her candidacy, emphasizing she is not a socialist, even though she has worked on several issues with Sen. Bernie Sanders, I-Vt., who has also mounted a campaign.

"I'm a Democrat," she said. "I'm proud of that."

She also said Hillary Clinton, who has ruled out her own 2020 run, can be a "strong voice" heading into the election season, but dismissed a question over whether former Vice President Joe Biden would "take over" the field of candidates if he gets into the race.

"I don't think it's fair to say, when you have so many excellent people running, that any one person will take over the field," Klobuchar said.
