House Judiciary Chairman Jerry Nadler (D-N.Y.) filed a lawsuit Wednesday to enforce a subpoena compelling former White House counsel Don McGahn to testify in the committee's investigation of President Trump's potential obstruction of justice.
Why it matters: McGahn, a key witness in former special counsel Robert Mueller's investigation who sat for more than 30 hours of interviews, has been blocked by the White House from complying with the subpoena, which was issued in April. In a letter to House Democrats, Speaker Nancy Pelosi stated that the McGahn lawsuit is part of the process of gathering "all the relevant facts" for the House to consider "whether to exercise its full Article I powers, including a constitutional power of the utmost gravity — articles of impeachment."
Most U.S. cities are at risk of experiencing extreme heat thanks to the "urban heat island effect" that's causing cities to warm as much as 50% faster than the rest of the country.
Why it matters: July was the hottest month ever recorded globally, and it was especially brutal for major metros.
