Legendary rocker Bruce Springsteen is the latest to join the growing list of people who are canceling plans to travel to North Carolina due to its so-called "bathroom law."

Springsteen announced Friday that he is canceling his Sunday show in Greensboro, N.C., to "show solidarity" with the people who oppose the law, which requires transgender people to use restrooms according to what's listed on their birth certificate and not the gender they identify as.

"To my mind, it's an attempt by people who cannot stand the progress our country has made in recognizing the human rights of all of our citizens to overturn that progress," the "Born to Run" singer said in the statement.

"I feel that this is a time for me and the band to show solidarity for those freedom fighters. As a result, and with deepest apologies … we have canceled our show scheduled for Sunday, April 10th. Some things are more important than a rock show and this fight against prejudice and bigotry — which is happening as I write — is one of them," Springsteen said.

The law, signed by Republican Gov. Pat McCrory in March, also prevents cities from passing anti-discrimination regulations to protect gay and transgender people.

Washington, D.C., Mayor Muriel Bowser last week banned city employees from official travel to the state. New York Gov. Andrew Cuomo similarly banned all non-essential official state travel.

"To ensure a constant voice in policy and practice in the District of Columbia that is in favor of equal treatment for members of the LGBTQ communities, no officer or employee of the District of Columbia is authorized to approve any official travel to North Carolina," Bowser said in a statement.

On Monday, the White House chimed in to say there are "policy and legal questions" raised by the North Carolina law. Press secretary Josh Earnest said the White House is mulling a response to the LGBT law.
