Blake was running against Foggy Nelson. But when they meet each other they both decided they liked each other, even though they were political rivals. Foggy lost his bid for re-election to Blake. Blake took up his position as D.A.
D.A Tower was about to unveil the new Worldwide Habitual Offender Computer to the press when they founds the door to this super-computer locked. Breaking it open, they found that Dr. Armstrong Smith, one of the developers of the computer, dead in the room. Spider-Man took it upon himself to solve the murder.
When J. Jonah Jameson accused Spider-Man of murder, Spider-Man went to Blake's office to deny the accusation. When Tower asked whether the accusation was true, Spider-Man replied that it was not. Tower recommended Spider-Man sue Jameson for defamation of character, but such a lawsuit would require that Spider-Man reveal his secret identity. This was unacceptable to Spider-Man, and he shattered Tower's desk in frustration. Tower accepted Spider-Man's apology and then told Spider-Man that he couldn't offer legal advice.
Handing Spider-Man a letter addressed to him care of Tower's office, he requested that Spider-Man not use city hall as his mail box. Thanking Tower for everything, Spider-Man departed. When Spider-Man and Jameson were shackled together, Blake decided that they should should be taken somewhere safe, Spidey refused to accept letting Smythe win and escaped with Jameson.

He was involved in the trial against Punisher. He told the court that he believed that Castle should be tried for all of his crimes as he willingly committed them. However, the defense argued that since the murder of his family Frank Castle has gone completely insane and needed to be institutionalized. Upon hearing this, Frank refused to believe that he is mad and lashed out, telling the judge that the entire system is crazy for letting criminals walk the street before collapsing in a nervous breakdown.
Louise Mason, a former super-heroine, managed to get hired by Tower as a legal secretary. In that role, she convinced Tower to hire Jennifer Walters, the She-Hulk, as a lawyer. Unfortunately, her super-hero life got in the way when the defense counsel argued that it influenced the jury in her favor, andTower, realizing the power of this argument in future cases, had to let She-Hulk go. Mason, who had become She-Hulk's friend, also decided to quit and help Jen set up her new practice. Before long, however, Tower had to call Jennifer and Louise again to handle a case no one else could. As the two women handled the unusual case, they were reinstated at the office as if they'd never even left.
She-Hulk worked with Tower for years,[note 1] but he began to get stressed about the frequent drama she caused with her superhero life. So much so, that his health had been affected and he had aged beyond his years.
After Jennifer lost another case over the excuse that her Avengers' activities had influenced the jury, Tower had to let her go once more, claiming he couldn't handle the pressure anymore.
