WASHINGTON (AFP) - The governor of the conservative southern US state of Alabama resigned on Monday (April 10), shortly after lawmakers began impeachment proceedings linked to his affair with a senior aide that was made public in humiliating detail.
Robert Bentley, 74, pleaded guilty in an agreement with prosecutors to two misdemeanour campaign violations and is barred from seeking public office again.
"I have spent the last year in deep and earnest prayer over our state and our people. I pray every morning for wisdom and guidance and forgiveness for the sins I have committed," the former dermatologist and church deacon told a news conference announcing his resignation.
But he did not directly acknowledge his romantic relationship with 45-year-old political adviser Rebekah Caldwell Mason, who is married.
The relationship between Bentley and his aide became a topic of speculation in 2015, when his wife of 50 years, Dianne, abruptly filed for divorce.
The scandal broke last year when the state's top police officer - fired by Bentley - provided news organisation AL.com with salacious details of the secret romance.
The media outlet reported on a 2014 phone conversation between Bentley and a woman he called Rebekah that was secretly captured by Dianne Bentley.
"When I stand behind you, and I put my arms around you, and I put my hands on your breasts... and just pull you real close...I love that, too," the governor is heard saying.
"Baby, let me know what I am going to do when I start locking the door," he said in another part of the tape. "If we are going to do what we did the other day, we are going to have to start locking the door."
Last week, an impeachment investigation report prepared for the Alabama House Judiciary Committee said Bentley tried to cover up the affair "in a process characterised by increasing obsession and paranoia".
"To ensure the silence of his staff, Governor Bentley encouraged an atmosphere of intimidation," it added. "Concern over the recordings appears to have become an obsession."
The report revealed that Bentley once opened the door of his hotel room in Washington clad in boxer shorts, thinking Mason was outside when it was actually the hotel staff.
On the same trip in 2014, his wife attended a group dinner with her husband and Mason, and saw the text messages he was sending his mistress while seated next to his wife. One of the messages said: "I can't take my eyes off you."
Bentley once mistakenly sent his wife a text message that said "I love you Rebekah," accompanied by a red-rose emoji.
Dianne Bentley was able to access other text messages sent by her husband because he had given her his state-issued i-Pad, not realising texts from his iPhone would show up on her tablet because the devices were linked.
As part of his plea deal, Bentley must surrender US$37,000 (S$52,048) in campaign funds and perform 100 hours of community service.
He pleaded guilty to failing to properly report a US$50,000 loan made to his campaign, and using campaign funds to pay nearly US$9,000 for Mason's legal fees last year.
Lieutenant Governor Kay Ivey was sworn in as governor on Monday evening.
