The general manager of the U.S. team in the 4 Nations Face-Off hockey tournament said he would welcome a visit from President Donald Trump to the championship game between the United States and Canada on Thursday night.

Guerin was asked whether the Canadian crowd booing the U.S. national anthem, a direct result of the political tensions sparked by President Donald Trump's threats to impose significant tariffs on Canada and repeated suggestions it should become America's 51st state, contributed to the intense first game and Team USA's performance.

President Donald Trump called the U.S. hockey team on Thursday to wish players good luck ahead of their 4 Nations Face-Off final against Canada. USA Hockey posted a photo on social media showing general manager Bill Guerin standing in the middle of the locker room holding up a phone.
