Danile Sickles had received numerous perquisites in jail, including being allowed to retain his personal weapon, and received numerous visitors.

So many visitors had come that he was granted the use of the head jailer's apartment to receive them.

They included many congressmen, senators, and other leading members of Washington society.

Sickles is charged with murder.

He secures several leading politicians as defense attorneys, among them Edwin M. Stanton, later to become Secretary of War, and Chief Counsel James T. Brady who, like Sickles, is associated with Tammany Hall.

Sickles pleads temporary insanity—the first use of this defense in the United States.

Before the jury, Stanton argues that Sickles had been driven insane by his wife's infidelity, and thus was out of his mind when he shot Key.

The papers soon trumpeted that Sickles was a hero for "saving all the ladies of Washington from this rogue named Key".

Sickles had obtained a graphic confession from Teresa; it was ruled inadmissible in court, but, was leaked by him to the press and printed in the newspapers in full.

The defense strategy ensured that the trial was the main topic of conversations in Washington for weeks, and the extensive coverage of national papers was sympathetic to Sickles.

Sickles had publicly forgiven Teresa, and "withdrew" briefly from public life, although he did not resign from Congress.

The public is apparently more outraged by Sickles's forgiveness and reconciliation with his wife, than by the murder and his unorthodox acquittal.
