Will President Trump participate in the House impeachment inquiry?

House Democrats have given President Donald Trump a Friday deadline to decide whether he wants to send lawyers or other representatives to participate in impeachment inquiry hearings. The White House has called the inquiry partisan and biased and declined to participate in Wednesday's hearing with four law scholars and college professors. But Trump has until 5 p.m. EDT on Dec. 6 to decide whether to take part in the process at all. Republicans hold a 53 to 47 majority in the Senate, so Trump doesn't expect the necessary two-thirds majority will vote to remove him. Over the past two months, House Democrats have led an impeachment inquiry into allegations Trump used the power of his office to pressure Ukraine to investigate one of his political rivals.

Did you get a visit from St. Nick?

For most Americans, Dec. 6 is just another winter day. But some — especially in the Midwest — will be checking their stockings to see what St. Nick has brought them as they celebrate St. Nicholas Day. The tradition originated as the feast day of St. Nicholas in the Catholic Church and is still widely celebrated in Europe. Traditions vary, but many mark the day by leaving shoes or stockings for St. Nick to fill with treats such as oranges, chocolate coins and candy canes. In the U.S., the holiday is most prevalent in cities with strong German roots. "It's definitely a Midwest thing," Heather Grams told the Milwaukee Journal.
