Vance says he's joining wife Usha on trip to Greenland this week

Washington — Vice President JD Vance is joining his wife, second lady Usha Vance, on her trip to Greenland this week, he announced. 

The vice president's decision comes after Greenland's prime minister said planned trips there by top Trump officials are "highly aggressive," and as President Trump isn't backing down on his hopes to acquire the semiautonomous territory of Denmark. National security adviser Mike Waltz has also been expected to visit Greenland soon. 

"Hey guys, It's JD Vance, the vice president," Vance said in a video posted to social media. "And you know, there was so much excitement around Usha's visit to Greenland this Friday that I decided that I didn't want her to have all that fun by herself, and so I'm going to join her."
