US Vice-President Mike Pence says he is willing to take a lie-detector test to prove he did not write a damning New York Times anonymous article that rocked the White House last week.
Pence is one of several senior Administration officials who have publicly denied that they wrote the article.
The piece, headlined "I Am Part of the Resistance Inside the Trump Administration", claimed there had been discussions to invoke the 25th Amendment, which allows for removal of a president if he or she is deemed unfit to carry out the duties of their office. Donald Trump has demanded an investigation to identify the rogue staff member.
Pence told Fox News yesterday it would be for the President to decide if lie detectors should be used to find the culprit. But he said: "I would agree to take it in a heartbeat and would submit to any review the Administration wanted to do. The honourable thing to do here is for this individual to recognise that they are literally violating an oath," he said.
"If they are a senior administration official, that they are violating an oath - not to the President, but to the Constitution." He added: "It's all an effort to distract attention from this booming economy and from the president's record of success." On CBS's Face the Nation, Pence said Trump "is the most accomplished president of my lifetime, and I think already one of the most successful presidents in American history".
