(CNN) Rep. Duncan Hunter -- who is accused of illegally dipping into campaign funds to pay for vacations, video games and more -- will plead guilty in federal court on Tuesday, CNN confirmed on Monday.

"I'm going to change my plea to guilty," Hunter said in an interview with CNN affiliate KUSI. One of Hunter's attorneys, Devin Burstein, confirmed to CNN on Monday afternoon that the plea will be guilty.

"I think it's important that people know that I did make mistakes. I did not properly monitor or account for my campaign money," Hunter said.

"I am responsible for my campaign and what happens to my campaign money," he added.

Citing the reasons for his change of heart, Hunter said, "I think it's important not to have a trial for three reasons and those three reasons are my kids."
