Toronto-born musician Neil Young, who is also an American citizen, says he “may be barred” from entering the United States over comments he made about President Donald Trump.

In a post on his website on Tuesday, the singer-songwriter — who is set to tour in Europe this summer — said, “When I go to play music in Europe, if I talk about Donald J. Trump, I may be one of those returning to America who is barred or put in jail to sleep on a cement floor with an aluminum blanket.”
