The sheer scale of President Trump’s corruption and contempt for oversight can be dispiriting and daunting. But it’s also forcing congressional Democrats to find new ways to chip away at Trump’s anti-accountabilty fortress.

One such new effort concerns a topic that is rarely discussed — Trump’s abuse of the classification authority. And it could also have the salutary effect of pushing President Joe Biden in a positive direction, should he get elected.

For months, Sen. Chris Murphy (D-Conn.) has been working to pry loose the legal justification for Trump’s order of the assassination of Iran’s Maj. Gen. Qasem Soleimani in January. The White House sent Congress a formal notification of the killing under the War Powers Act just after it happened, but kept it classified — meaning the official rationale was kept secret.
