Former Florida governor Jeb Bush (R) said Thursday that just because his son says he is likely to run for president doesn't mean it's true.

"He's got an opinion, he didn't talk to me," Bush told NBC News Wednesday evening. "When you have kids you'll probably have the same frustration, you love them to death and they have their own opinions -- but I'll make up my mind just as I've said, at the end of the year."

George P. Bush told ABC News on Sunday that his father is “moving forward” toward a run and is "more than likely" to enter the race.

While Jeb Bush has left the political world guessing about his intentions, he is sounding like candidate on the midterm campaign trail this week.

He took a swipe at Hillary Clinton in Colorado on Wednesday. In Tennessee on Tuesday, Bush blamed the unpopularity of Common Core education standards on President Obama taking credit for them.

Conservatives have turned sharply against Common Core in recent months. Bush backs the standards.
