A federal judge on Monday dismissed and declared moot a lawsuit by former deputy national security adviser Charles Kupperman, who was seeking a ruling on whether to comply with a subpoena in the House's impeachment inquiry or a directive from the White House blocking his testimony.
The big picture: The House committees conducting the investigation into President Trump's dealings with Ukraine withdrew Kupperman's subpoena in November, believing that they could move forward with impeachment without getting tangled up in a prolonged court battle.
16-year-old Swedish climate activist Greta Thunberg told BBC Radio 4 on Monday that she wouldn't have wasted her time meeting with President Trump at September's UN climate summit in New York.
"Honestly, I don’t think I would have said anything because obviously he’s not listening to scientists and experts, so why would he listen to me? ... So I probably wouldn’t have said anything. I wouldn’t have wasted my time."
Former Vice President Joe Biden tweeted Saturday he wanted to clarify comments he made to The Des Moines Register that he would defy a subpoena to testify in President Trump's Senate impeachment trial. But he didn't make clear whether he would testify.
Why it matters: Biden told the news outlet his testimony would take all of the focus off Trump, allowing the president would be able to get away with violating the Constitution. This is a move straight out of Trump's career playbook, according to Biden.
