This guy did

"On January 22, 1987, the day before his sentencing, Dwyer called a press conference to "provide an update on the situation." Many expected Dwyer to announce his resignation from office.
At the conference, an agitated and nervous Dwyer once again professed his innocence, and declared that he would not resign as state treasurer.At this point, Dwyer stopped with his prepared text and called to three of his staffers, giving each an envelope. One of the envelopes contained a suicide note to his wife. The second contained an organ donor card and other related materials. The third contained a letter to Robert P. Casey, who had taken office only two days before.
After handing out the envelopes, Dwyer opened a manila envelope and withdrew a .357 Magnum revolver, advising those in the crowd, "Please leave the room if this will offend you." Those in attendance cried out to Dwyer, pleading with him to put the gun down ("Budd, don't do this!" and "Budd, listen to me!" were heard on television). Some tried to approach him. "Don't, don't, don't, this will hurt someone," he warned.[4] Amid the cry of "Budd, Budd, Budd!" Dwyer put the gun barrel into his mouth and pulled the trigger. He collapsed against a wall in a sitting position, blood pouring from his nose, all in front of five television news cameras while the people are screaming and using profanity in shock. Dwyer was declared dead at the scene at 11:31 a.m."
"Budd Dwyer graduated from Allegheny College in Meadville, Pennsylvania. He went on to get his master's degree in education and taught social studies and coached football at Cambridge Springs High School. As a Republican, Dwyer served as a member of the Pennsylvania House of Representatives from 1965 to 1970 and the Pennsylvania Senate from 1970 to 1980. After his tenure as a senator, Dwyer moved on to the treasurer's office, a position he held up to his death."
