This post has been corrected.
With his announcement Tuesday that he is resigning from Congress, Rep. Aaron Schock (R-Ill.) appears to become the youngest member of the House or Senate to have resigned his seat before the end of a Congress in American history.
Using data from GovTrack, it seems that 33-year-old Schock is the youngest by a decent margin. In second place, John Brown, who left the House to sit in the Senate in 1792 at the age of almost 35 years. (Schock turns 34 in May.) Others on the list of the youngest to resign have names that are more familiar than Brown's; many did so to move to the upper chamber.
If we're talking only about members who have resigned over alleged wrongdoing, Schock is the youngest by four years; Trey Radel resigned at age 37 last year over a cocaine arrest.

Being the youngest to resign would be the second distinction we've awarded to Schock; he's also the first Millennial to have made it to Capitol Hill. There have only been 10 members of Congress who are from his generation (born in 1980 or later), meaning that a full one-10th of congressional Millennials have resigned early under a cloud of scandal. Make of that what you will.
Correction: This post originally indicated that Walter Tucker left office due to death. Happily, he is still alive, though his departure from Capitol Hill was a bit more scandalous. My apologies.
