White House press secretary Sean Spicer on Tuesday dismissed concern about the U.S.-German relationship after Chancellor Angela Merkel questioned whether Germany could "fully" depend on the U.S.

"I think the relationship that the president has had with Merkel he would describe as fairly unbelievable," Spicer told reporters. "They get along very well. He has a lot of respect for her. They continue to grow the bond that they had during their talks in the G-7."

Both were in Brussels for the NATO summit and then the G-7 summit in Sicily at which the assembled leaders could not reach an agreement with Trump on climate change.

"The times in which we can fully count on others are somewhat over, as I have experienced in the past few days," Merkel was quoted by the Associated Press as saying at a campaign appearance Sunday. "And so all I can say is that we Europeans must really take our destiny into our own hands."

Spicer on Tuesday said Merkel's comments were not meant to indicate a loss of faith in the U.S. but rather that NATO's other members were preparing to invest more in the alliance – something Trump has repeatedly sought, including during a speech before the alliance last week.

"That's what the president called for. He called for additional burden-sharing," Spicer said. "The secretary-general of NATO said that the president's calls are what's moving them in the right direction. The president is getting results. More countries are stepping up their burden-sharing. That is a good thing for them. It's a good thing for NATO, and it's a good thing for America."

Spicer's comments came after Trump on Tuesday morning appeared to react to Merkel's criticism by tweeting that Germany was coming up short in its responsibilities to NATO and was swindling the U.S. on trade.
