He also dubbed it "an extremely interesting conversation" but when asked what was discussed he only said "to be continued" before leaving.

Gore says he also met with Ivanka Trump, the president-elect's daughter. Transition officials said earlier Monday that the two would discuss climate change, which is Gore's signature issue.

The president-elect called man-made climate change a hoax and has pledged to undo a number of regulations to protect the environment.

The White House says progress in the United States' relationship with China could be "undermined" if the issue of Taiwan's sovereignty flares up.

The comments from White House spokesman Josh Earnest follow President-elect Donald Trump's phone call last week with Taiwan's president.

Earnest says Obama administration officials have been in touch with their Chinese counterparts to reiterate the U.S. support for the "One China" policy. The policy does not recognize Taiwan as a sovereign nation.

Earnest says it's "hard to determine" what Trump's aims were in speaking to Taiwan's leader. He also said it's unclear whether it helps Taiwan if this issue is raised.

Iowa Gov. Terry Branstad is meeting with President-elect Donald Trump this week amid speculation he could become the next U.S. ambassador to China.

Branstad told reporters Monday he has a tentative appointment to meet with Trump while the Republican governor is in New York for an economic development trip scheduled from Tuesday to Thursday.

At a rally in Sioux City, Iowa, before the election, Trump had praised Branstad's knowledge of trade and called him a "prime candidate to take care of China."

Branstad said Monday that Trump hasn't offered him a position. Although Branstad didn't directly reference becoming U.S. ambassador to China, he told reporters he's had discussions recently with his family about possibly moving to China.

Trump won Iowa and will hold a rally Thursday in Des Moines.

12:05 p.m.

District of Columbia Mayor Muriel Bowser is scheduled to meet with President-elect Donald Trump.

LaToya Foster, a spokeswoman for Bowser, said the mayor will meet with Trump, at her request. Foster says the issues on the agenda are public safety, education, unemployment, infrastructure and D.C. statehood.

Bowser, a Democrat, has noted that 93 percent of District residents voted for candidates other than Trump, and that "some mending of relationships" is needed.

Bowser skipped the highly publicized grand opening of Trump's hotel.

House Majority Leader Kevin McCarthy says imposing tariffs on companies that move their operations overseas could result in a trade war.

President-elect Donald Trump said Sunday he'd impose a 35 percent tax on companies that close U.S. factories, then relocate abroad and try to sell their products back to the United States.

Republicans have long opposed such an approach, and it would likely need congressional approval.

McCarthy tried to downplay suggestions that Trump's proposal flew in the face of long-held GOP principles.

But he said that comprehensive tax reform would be a better way of keeping companies and jobs in this country.

"I think that's a better way of solving the problem than getting into a trade war with a 35 percent tariff," the California Republican told reporters at the Capitol Monday.
