(Slate) -- President Donald Trump keeps giving the House of Representatives excellent reasons to begin an official impeachment inquiry.
The latest came on Monday when Trump and some members of his family filed a lawsuit to quash subpoenas asking Deutsche Bank and Capitol One to turn over financial records concerning the Trumps and their business. The president argues that House Democrats issued the subpoenas for illegitimate reasons unconnected to any formal business of Congress. This argument is quite weak under Supreme Court precedent, since Congress has broad constitutional authority to conduct investigations. But if Democrats are worried about making the case in court that their subpoenas are tethered to a legitimate congressional function, they have a simple solution at hand: Admit that these subpoenas may serve as a prelude to impeachment.
No one seriously questions Congress’ power to issue subpoenas as part of its oversight duties. But Trump’s lawyers insist that these subpoenas, which have not yet been released to the public, go too far. They were, Monday’s lawsuit alleges, “issued to harass” the president, “to rummage through every aspect of his personal finances” to locate “material that might be used to cause him political damage.” Because “no grounds exist to establish any purpose other than a political one,” the suit claims, the federal courts must prohibit the banks from complying with the subpoenas.
