US District Judge Amit Mehta knocked down Trump’s application to quash the subpoena of his accountants’ records. Judge Mehta wrote a 41-page opinion. The gist of it is this:

“It is simply not fathomable that a Constitution that grants Congress the power to remove a sitting President for reasons including criminal behavior would deny Congress the power to investigate him for unlawful conduct—past or present—even without formally opening an impeachment inquiry.”

In a nutshell, the Judge ruled that if Congress expresses a legitimate purpose for its investigation, it is not for the court – or the President – to second-guess it.

The same reasoning applies to other subpoenas issued by the House and Senate committees.  It remains to be seen if Trump will continue to resist the House’s investigations. If Mehta’s ruling stands, and it probably will, Trump’s continued refusal itself is a reason for impeachment, which the House will be constrained to undertake.
