LONDON — The parents of a extremely sick baby stormed out of court during a hearing Thursday to decide whether their son can receive experimental treatment they believe could save his life.

The plight of Charlie Gard has garnered worldwide attention and been highlighted by President Donald Trump and Pope Francis.

Parents Chris Gard and Connie Yates left the court after reacting to comments made by Judge Nicholas Francis.

Charlie’s father said: “I thought this was supposed to be independent,” as the couple left the courtroom two hours into the hearing, NBC News’ U.K. partner, ITV News, reported.
