Senator Van Hollen tweeted Monday that “United must do more than “apologize,” saying there needs to be a full investigation.
#United must do more than "apologize". Full investigation needed. Airlines must start treating passengers with respect, not like cargo.

Munoz issued an official statement Tuesday after his initial apology was met with backlash. His statement read, in part, "I deeply apologize to the customer forcibly removed and to all the customers aboard. No one should ever be mistreated this way. I want you to know that we take full responsibility and we will work to make it right."
