Story highlights Trump said Tuesday that it would be fair for the media or rivals to investigate his background

"Yes, they would be," he said in response to a question about his personal "indiscretions"

Washington (CNN) If Democratic or Republican opponents want to drag some of the sordid details from Donald Trump's personal life onto the campaign trail, that's fine by him.

The GOP presidential front-runner said Tuesday that it would be fair for the media or rivals to investigate his background, similar to how he's bringing up Bill Clinton's personal life in attacks against his wife, Hillary Clinton.

"Yes, they would be," he said in response to a question about his personal "indiscretions" while speaking to reporters aboard his personal plane before a rally in Iowa.

Trump didn't go into specifics, and reporters didn't follow up on the question. But his personal life at times has been tabloid fodder, most famously in the early 1990s when his marriage to his first wife, Ivana Trump, fell apart after he had an extramarital affair with model and actress Marla Maples. Trump eventually married Maples in 1993, and the two divorced six years later. Trump married his current wife, Melania, in 2005.
