Good morning, NBC News readers.A top State Department official described the White House actions on Ukraine as “injurious to the rule of law,” another billionaire might jump into the 2020 presidential race, and 21 movies and TV shows to escape from it all over the holidays.Here’s what we’re watching today.Diplomat says Putin, Orban, Giuliani ‘shaped the president’s view of Ukraine’George Kent, a senior State Department official responsible for Europe, told House investigators that Russia’s President Vladimir Putin, Hungary’s Prime Minister Viktor Orban and Trump’s personal lawyer Rudy Giuliani talked the president into a negative view of Ukraine and its new leader.The transcript of Kent’s testimony released Thursday feeds into longstanding concerns from national security experts that the president’s views on key foreign issues are being influenced by Putin and other autocratic leaders like the far-right leader of Hungary.In his testimony, the deputy assistant secretary of state also took aim at Giuliani for his role in leading a smear campaign against Marie Yovanovitch, the ousted U.S. ambassador to Ukraine.Meantime, House Democrats subpoenaed Mick Mulvaney to testify Friday as part of the impeachment inquiry.The acting White House chief of staff is expected to be a no-show, falling in line with several other officials who were ordered by the president not to cooperate with the investigation.Anonymous author writes Trump’s decision-making is eroding over timeThe president’s behavior can be so erratic that most top administration officials have pre-written resignation letters ready to submit, an anonymous author claiming to be a senior official in the Trump administration says in a book scheduled to be published this month.To complicate matters, the president’s decision-making abilities are getting worse with time, according to excerpts of “A Warning” that were obtained and read Thursday night on MSNBC’s “The Rachel Maddow Show.”In the book excerpts, the author describes the near-daily “five-alarm fire drill” that leads senior officials to cancel plans and race to the White House to intercept Trump before he can enact his latest “wacky or destructive idea.”The information is coming from an anonymous source, and NBC News does not know who the writer is nor whether they were in a position to have witnessed what they say transpired.Mike Bloomberg prepares a possible 2020 presidential bidThe former three-term mayor of New York and billionaire businessman is positioning himself to enter the Democratic presidential primary, though he has not yet made a final decision.In a sign that he is seriously considering a run, Bloomberg was collecting signatures in Alabama, in order to qualify for the primary there.

Weeks later, the state took custody of both of Melissa Bright’s children, as she pleaded with Child Protective Services not to remove them from her home.The Bright family’s case is just one example of how doctors’ opinions can have an extraordinary influence over child welfare decisions.Those conclusions sometimes trigger questionable family separations and criminal charges, an NBC News and Houston Chronicle investigation found.The Week in PicturesPatrick Semansky / APTrump hugs Washington Nationals catcher Kurt Suzuki during an event to honor the 2019 World Series champions at the White House on Monday.
