Outgoing U.S. President Donald Trump on Thursday condemned violence that ravaged the Capitol a day earlier, while vowing to ensure an orderly transition of power.

"Like all Americans I am outraged by the the violence, lawlessness, and mayhem," Trump said in taped remarks posted on Twitter. "And to those who broke the law, you will pay."

The president went on to acknowledge the congressional certification of President-elect and Democrat Joe Biden's victory in their White House race in 2020.

"Now Congress has certified the results. A new administration will be inaugurated on January 20. My focus now turns to ensuring a smooth, orderly and seamless transition of power," he said. "This moment calls for healing and reconciliation."
