President Donald Trump’s national security adviser promised a “very professional transition” to the administration of President-elect Joe Biden in an interview broadcast Monday, even as Trump continues to falsely claim he won the November election. Speaking to the Global Security Forum hosted in part by Qatar, Robert O’Brien several times mentioned the transition and referred to recent peace deals that Bahrain, Sudan and the United Arab Emirates struck with Israel as “a great legacy for the president to have as he leaves office.”
