The Latest: From the air, Trump tweets about trade

President Donald Trump is recapping his first foreign trip and saluting U.S. military personnel at an event before he returns to Washington.

Trump told U.S. military personnel in an address at Naval Air Station Sigonella in Sicily that "you are protecting us and we will always remember that."

The first lady also thanked the service members for sacrificing on behalf of the U.S. She says it's because of their "selfless commitment" and the sacrifices their families make that Americans are able to enjoy many freedoms.

Trump's campaign team says the rally planned for Thursday has been postponed "due to an unforeseen change" in the president's schedule.

Vice President Mike Pence is scheduled to headline a fundraising "Roast and Ride" event in Iowa for Sen. Joni Ernst next Saturday.

President Donald Trump's top advisers are refusing to address reports that his son-in-law and a top Russian diplomat may have discussed setting up a secret communications channel.

In a press conference in Sicily, Saturday, advisers H.R. McMaster and Gary Cohn declined to comment on new revelations about Jared Kushner's communications with Russia's ambassador to the U.S., Sergey Kislyak (SER'-gay KISS-lee-yak).

The Washington Post reported Friday that Kislyak told his superiors that he and Kushner discussed setting up a back channel between Trump's transition team and the Kremlin.

President Donald Trump's top national security adviser says it's a "matter of fact" that the United States stands behind NATO's common defense principle.

Trump was sharply critical of NATO prior to his inauguration, calling the alliance "obsolete" but has since expressed support for it.

The White House says G-7 leaders had a "very robust" conversation before issuing a final statement giving President Donald Trump more time to decide whether to keep the U.S. in the Paris climate agreement.

President Donald Trump says he'll make a final decision next week on whether the U.S. will stay in the Paris climate agreement.

Nearly every nation that signed the 2015 agreement has agreed to curb greenhouse gas emissions.

Trump's pending review of U.S. climate policies has left environmentalists bracing for the possibility of bland G-7 promises that say little after years of increasingly stronger commitments to reduce reliance on fossil fuels and cut greenhouse gas emissions.

Tensions recently escalated between the two countries after the Trump administration imposed new tariffs on softwood lumber from Canada and railed against its pricing of domestic milk to cover more dairy ingredients, which impacts U.S. dairy producers.

The president supports ongoing efforts to push member countries to spend at least 2 percent of their gross domestic product on defense.

First on the list, of course, is terrorism.

The trip has gone off without a major misstep, with the administration touting the president's efforts to create a new coalition to fight terrorism while admonishing partners in an old alliance to pay their fair share.
