Sullenberger, who admits that he also had a stutter, began the piece by reflecting on his childhood in Denison, Texas, and how hard speaking in class was for him.

"Those feelings came rushing back, when I heard Lara Trump Lara Lea TrumpHillicon Valley: Democrats demand answers over Russian interference bulletin | Google Cloud wins defense contract for cancer research | Cyberattack disrupts virtual classes Lara Trump campaigns with far-right activist candidate Laura Loomer in Florida Sunday shows - Democrats target Trump as violence flares MORE mocking former Vice President Joe Biden at a Trump campaign event, with the very words that caused my childhood agony," he wrote.

"'Joe, can you get it out?' Ms. Trump was seen saying onstage, as a few giggles are heard from an otherwise silent audience. 'Let’s get the words out, Joe,'" he continued.

Sullenberger disclosed that he attended a campaign fundraiser for the 2020 Democratic hopeful last year but added that Lara Trump's words go "beyond politics."

"Stop. Grow up. Show some decency. People who can’t, have no place in public life," he wrote, seeming to direct his words at President Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE's daughter-in-law.

The retired pilot then said his stutter didn't stop from being an "Air Force fighter pilot, an airline pilot, or even a public speaker."

He concluded with a message for children who struggle with stuttering: "You are fine, just as you are. You can do any job you dream of when you grow up."

"You can be a pilot who lands your plane on a river and helps save lives, or a president who treats people with respect, rather than making fun of them," he continued.
