I wrote today about the FBI’s counter-intelligence investigation of the president:

The Times story is another sign that we have forgotten the role of our respective branches of government. It is Congress that exists to check and investigate the president, not the FBI. Congress can inveigh against his foreign policy and constrain his options. It can build a case for not reelecting him and perhaps impeach him. These are all actions to be undertaken out in the open by politically accountable players, so the public can make informed judgments about them.
Perhaps the Times report is exaggerated, or the FBI has serious evidence of a criminally corrupt quid pro quo between Trump and Moscow that there’s no public indication of yet.
Otherwise, the Times story is a damning account of an offense against our political order, and not by Donald Trump.
