Bill Clinton: 'Plenty of time' to address Trump's criticism if businessman becomes GOP nominee

CEDAR RAPIDS, Iowa — Former President Bill Clinton says there will be "plenty of time" to discuss Donald Trump's criticism of his past transgressions if the billionaire businessman becomes the Republican nominee.

Clinton is making his first trip solo trip to Iowa to campaign for his wife Hillary Clinton, the front-runner for the Democratic nomination. Asked by a reporter about Trump's recent comments about him, the former president said he doesn't want to do anything now except help his wife's campaign.

Clinton spoke as he wrapped up a stop at a local market where he spent an hour shaking hands with patrons, taking dozens of selfies and sampling the local fare, including a fruit and vegetable smoothie.

Trump has been raising concerns about the former president's impeachment by the House and decades-old sex scandals.
