Republican primary front-runner Donald Trump on Sunday explained why he gave a quarter of a million dollars to the Clinton Foundation before he ran for president.

“I did give to the Clinton Foundation. What I didn’t know is they’d be using it for private aircraft and things like that,” Trump said on “Fox News Sunday.”

“The Clinton Foundation was helping with Haiti and with lots of other things, and I thought it was going to do some good work, so it didn’t make any difference to me,” he added.

The real estate mogul also pointed to his business interests in cultivating support among politicians from each party.

“Again, I was a businessman, and it was my obligation to get along with everybody, including the Clintons, including Democrats and liberals and Republicans and conservatives,” he said. “As a businessman, I had an obligation to do that.”
