Romney: 'I will tell my children I did my duty'
Mitt Romney is addressing the Senate chamber, giving his reasons for voting against his party and the president.
"I'm aware that there are people in my party in my state who strenuously disapprove of my decision," he says.
"I'm sure I'll hear abuse from the president and his supporters," he adds, saying that his decision was made after much praying.
“I believe that attempting to corrupt an election to maintain power is about as egregious an assault on the Constitution as can be made. And for that reason, it is a high crime and misdemeanor and I have no choice under the oath that I took but to express that conclusion."
"We've come to different conclusion fellow senators, but I trust we have all followed the dictates of our conscious".
He concluded: "I will only be one name among many - nor more, no less - to future generations who look back ... I will tell my children I did my duty to the best of my ability.
