Captain Chesley “Sully” Sullenberger, the retired pilot who safely landed an airplane on the Hudson river in 2009, slammed Lara Trump in an op-ed on Saturday.

“Whether you stuttered as a child or laughed at one who did; whether as a parent you try to protect your own stuttering child from taunts such as those made by the president’s daughter-in-law; these words come without hesitation: Stop. Grow up. Show some decency. People who can’t have no place in public life,” Sullenberger, 68, wrote in the New York Times.
