Good morning, NBC News readers.From new revelations to analysis, we’ve got full coverage of the first public hearings of the impeachment inquiry into President Donald Trump.Impeachment hearings Day 1: Here’s what we learnedBill Taylor and George Kent, the first two witnesses in the House impeachment inquiry into Trump’s dealings with Ukraine, testified for more than five hours Wednesday.The most significant new development came from Taylor, the top U.S. diplomat in Ukraine, when he testified about a previously undisclosed phone call between Trump and U.S. Ambassador to the E.U. Gordon Sondland.In the phone call, overheard by one of Taylor’s staffers, Trump asked Sondland about “the investigations” into the Bidens and the 2016 election, Taylor testified.Taylor said that he only learned about the conversation that puts the president more squarely in the center of the swirling scandal recently and did not name the staffer who reported the call.But two sources familiar with the matter told NBC News that it was David Holmes, a State Department official whose name was recently added to the calendar to testify in a closed deposition on Friday.Here are some of the other key things we learned from the first day of public testimony.Trump, meanwhile, largely sought to appear above impeachment drama — sticking to his scheduled counter-programming schedule of White House events.The president claimed he was “too busy” to watch the proceedings, spending much of the day in meetings with Turkey’s President Recep Tayyip Erdogan.In a news analysis, NBC News’ Jonathan Allen argues that the first day of hearings offered plenty of substance, but little of the “pizazz” necessary to capture public attention.The next public impeachment hearings will happen on Friday when the former ambassador to Ukraine Marie Yovanovitch is expected to testify.Democrats are calling for Stephen Miller to resign after leak of xenophobic emailsSeveral prominent Democrats have called for White House senior adviser Stephen Miller to resign following the release of emails in which he purportedly linked to white nationalist websites.The Southern Poverty Law Center released a cache of hundreds of emails Tuesday leaked by a former Breitbart writer who corresponded with Miller between 2015 and 2016.Let our news meet your inbox.
