Vice President Mike Pence says he’d have no problem taking a lie detector test to prove he isn’t part of an anti-Trump “resistance” in the administration. In an interview with Fox News Sunday, Pence said he’d agree to take a polygraph test “in a heartbeat and would submit to any review the administration wanted to do.” “The honorable thing to do here is for this individual to recognize that they are literally violating an oath,” Pence said of the anonymous author of the piece. “If they are a senior administration official, that they are violating an oath, not to the president, but to the Constitution,” he said. The op-ed portrayed Trump as incompetent and reckless, suggesting unnamed aides are secretly working to mitigate disastrous decisions by the president. Trump has called on the Justice Department to investigate the source of the op-ed, which he has equated with treason. Pence backed the president in that regard, saying there may be a legal basis to opening an investigation. “To have an individual who took that oath [to the Constitution] literally say that they work every day to frustrate the president advancing the agenda he was elected to advance is undemocratic. It’s not just deceitful. It’s really an assault on our democracy,” Pence said Sunday.
