London: The parents of British teenager Harry Dunn met with President Donald Trump at the White House, only to be told that the woman British police say was involved in the car crash that killed their son was ready to meet them.

Dunn, 19, was killed on August 27 when his motorcycle was involved in a collision with a car that police say was driven by American 42-year-old Anne Sacoolas, who was allegedly driving on the wrong side of the road at the time. Sacoolas, who is the wife of a US government official, claimed diplomatic immunity under international law which allowed her to return to the United States.

Appearing on CBS This Morning on Wednesday, Dunn's parents, Charlotte Charles and Tim Dunn, described the meeting, explaining that they had no idea they were meeting with the President and had been invited to the White House to meet with "a senior official."

"The bombshell was dropped ... soon after we walked in the room," Charles said.
