Bruce Springsteen is no stranger to voicing his opinion on social issues. Last year, the singer performed a tribute to Eric Garner, Michael Brown, and Freddie Grey at the Shining a Light concert organized as a reaction to a string of violence and mass shootings.

During an interview published in the latest issue of Rolling Stone, Bruce Springsteen called Republican presidential nominee Donald Trump a “moron” while also explaining his thoughts on the Black Lives Matter movement.

“It’s all chickens coming home to roost,” he began. “These are issues that have been ignored or hidden, and due to modern technology and the availability of cellphone cameras and constant video feed, these things are coming to the surface. Black Lives Matter is a natural outgrowth and response to the injustices that have been occurring for a very long time in the United States.”

And, when asked to give his take on Colin Kaepernick’s controversial protest of the national anthem, Springsteen claimed that “athletics is a difficult place to make political statements.”

He added, “I think when politics or personal expression is injected, it rankles people more than in other fields. But we’re in a time where there isn’t any place where these issues can be excluded. I admire Kaepernick, but it’s a very difficult field to be outspoken in.”

Springsteen is currently promoting his new memoir, Born to Run, on sale now.
