President Trump's former national security adviser John Bolton alleges in his forthcoming book that the president explicitly told him "he wanted to continue freezing $391 million in security assistance to Ukraine until officials there helped with investigations into Democrats including the Bidens," the New York Times first reported.
Why this matters: The revelations present a dramatic 11th hour turn in Trump's Senate impeachment trial. They directly contradict Trump's claim that he never tied the hold-up of Ukrainian aid to his demands for investigations into his political opponent Joe Biden.
We are living in a measurably different political and media landscape than when the Senate acquitted President Bill Clinton of impeachment charges in 1999.
The big picture: These dynamics are setting the pace as President Trump’s legal team speeds through arguments to seek a fast acquittal.
British Prime Minister Boris Johnson is inching toward a decision that could profoundly harm the "special relationship" between Britain and the United States under President Trump.
Driving the news: Johnson is expected to decide, as soon as this week, whether to defy Trump's request that he ban Chinese technology giant Huawei from the U.K.'s 5G wireless network.
