There were gasps and laughter on the Senate floor when House impeachment manager Rep. Adam Schiff announced this: Even as Trump's lawyers insisted repeatedly, over and over, that a president cannot be impeached for refusing to comply with congressional subpoenas, his Bill Barr-led Department of Justice is in court, today, insisting that Congress absolutely can respond to a president refusing to abide by congressional subpoenas by ... impeaching that president.
CNN reports, "Justice Department lawyer James Burnham said without hesitation that the House can use its impeachment powers, among other options, like withholding appropriations." The courts have no role in enforcing subpoenas directed at the executive branch—that has been the repeated Trump court argument. In the Senate, in the meantime, Trump's team is simultaneously arguing that impeachment cannot be used in response to a president's team ignoring subpoenas, that it must be argued through the courts.
The Trump defense is inherently corrupt. The Republican defense, in the Senate, is inherently corrupt.
