With a little more than two weeks until the Iowa caucus, Republican presidential candidate Jeb Bush plans to make a stop in New York next week to talk about foreign affairs and raise money for his campaign.

Bush spent less than 48 hours this week in Iowa, making four public campaign appearances and meeting briefly with state GOP lawmakers. He isn't scheduled to be back in the Hawkeye State until closer to the the Jan. 28 Republican presidential debate in Des Moines, scheduled to be hosted by Fox News Channel.

Between now and then, Bush has a cross-country travel itinerary lined up. After Thursday night's Republican presidential debate in South Carolina, Bush returns to New Hampshire for events on Friday night, in Hollis, and Saturday in Amherst and Hampstead. The Bush team sees a strong performance in the Granite State as most critical to Bush's long-term success, so much so that it started airing two new TV ads in the state this week highlighting his family's struggle with drug addiction and his opposition to GOP front-runner Donald Trump.

Next week, Bush begins in the Big Apple. There's a big-dollar fundraiser scheduled in New York on Monday. On Tuesday, he has an afternoon event with the Council on Foreign Relations, where he is expected to give remarks and answer questions in a session moderated by Fred Hiatt, editor of The Washington Post's editorial page.

Bush has spent much of his time on the campaign trail discussing foreign affairs and national security as a way to distinguish himself from Trump and other rivals. The Council on Foreign Relations has been hosting conversations with several leading presidential candidates. New Jersey Gov. Chris Christie, Ohio Gov. John Kasich and former secretary of state Hillary Clinton have met with the group in recent months.

Later next week, Bush is slated to return to New Hampshire for events over six days in Keene, Hampton, Nashua and Rochester.

On Jan. 25 — exactly one week before the Iowa caucuses — Bush is scheduled to visit Houston for a campaign fundraiser before making his first solo campaign appearance in Nevada in more than two months. He was in Las Vegas last month for a GOP debate. The Silver State holds a Republican caucus in late February and is seen as the lesser of the first four contests.

On Jan. 26, Bush will visit Elko, a town closer to Salt Lake City than Las Vegas, for a town hall meeting.

From there, Bush's schedule remains in flux but is likely to include more stops in Iowa, aides said.
