(CNN) —  

Since news broke in March that Hillary Clinton used a personal email and private server during her time as secretary of state, she has tried explaining and defending herself against the controversy that followed.

On Tuesday, she finally apologized.

“I’m sorry about that,” Clinton said Tuesday during an interview on ABC News’ “World News Tonight with David Muir,” acknowledging that she should have used separate accounts for work and personal business. “I take responsibility and I am trying to be as transparent as I possibly can.”

Clinton began the long road to the apology in March by explaining that she had used her personal email “for convenience.”

Five months later, in August, she admitted, “these years later, it doesn’t look so convenient.”

Along the way, she touted the release of 55,000 pages of her emails.

“Everything I did was permitted,” she told CNN in July. “There was no law, there was no regulation, there was nothing that did not give me the full authority to decide how I as going to communicate.”

At the end of July and the beginning of August, her explanations turned to security.

“I never sent nor received any information that was classified at the time it was sent,” Clinton said.

Clinton also went through a period of exasperation with the story’s persistence. She joked with reporters about wiping the server with a cloth and downplayed the story by telling reporters, “Nobody talks to me about it, other than you guys.”

By the end of August, she changed her tone.

“It clearly wasn’t the best choice. I should have used two emails,” she said. “And I take responsibility for that decision.”

On Tuesday, during a taping of “The Ellen DeGeneres Show,” Clinton told the host, “I made a mistake, and I’m sorry for all the confusion that has ensued.”
