President Trump made an “unwavering” commitment on Thursday to locating Robert Levinson, a former FBI agent who vanished during a visit to Iran’s Kish Island in 2007.

“Today, we mark the ten-year anniversary of the disappearance of United States citizen Robert ‘Bob’ Levinson,” White House press secretary Sean Spicer said in a statement. “The Levinson family has suffered far too much during the last decade due to the absence of Mr. Levinson, a loving father, brother, husband, grandfather, and friend to many.”
