ABC News’ Betsy Klein reports: On the eve of her 60th birthday, Missouri Sen. Claire McCaskill said that she has officially buried the hatchet with Bill and Hillary Clinton.

McCaskill, who recently signed on to an effort to encourage Hillary Clinton to run for president in 2016, acknowledged that she was wrong to say in a 2006 “Meet the Press” appearance that “I don’t want my daughter near” Bill Clinton.

“I said a lot of things in the last 30 years that I’m not particularly proud of. I mean there have been things that I’ve said that I wish I could take back,” McCaskill said at an event in Washington, D.C. on Tuesday night sponsored by BuzzFeed. “It was gratuitous and hurtful and I have apologized to both President Clinton and Hillary Clinton for saying it.”

She conceded that her decision to endorse Barack Obama in the 2008 election was controversial, but she’s now thrown her support behind Hillary Clinton.

“I couldn’t be more enthusiastic for her to be president now,” the Missouri Democrat said in an interview with BuzzFeed’s John Stanton, “and I can’t wait to work as hard or harder for Hillary Clinton.”

McCaskill attributed her Obama endorsement to a conversation with her children, who she said, “got in my face a little bit.”

“It was impressive that my kids were able to crystallize the notion that I was worried about the implications of endorsing Barack Obama not because I didn’t think he’d be a wonderful president and inspiring for our country and do something that no other candidate could do for the United States of America,” she said, “but I was worried about endorsing him because of my career.”

The senator said her children also inspired her to start a Twitter account, which she manages on her own.

“No one on my staff has ever tweeted one character on my account,” she noted.
