George Conway writes for the Washington Post:
So it turns out that, indeed, President Trump was not exonerated at all, and certainly not “totally” or “completely,” as he claimed. Special counsel Robert S. Mueller III didn’t reach a conclusion about whether Trump committed crimes of obstruction of justice — in part because, while a sitting president, Trump can’t be prosecuted under long-standing Justice Department directives, and in part because of “difficult issues” raised by “the President’s actions and intent.”
The investigation that Trump tried to interfere with here, to protect his own personal interests, was in significant part an investigation of how a hostile foreign power interfered with our democracy. If that’s not putting personal interests above a presidential duty to the nation, nothing is.
White House counsel John Dean famously told Nixon that there was a cancer within the presidency and that it was growing. What the Mueller report disturbingly shows, with crystal clarity, is that today there is a cancer in the presidency: President Donald J. Trump. Congress now bears the solemn constitutional duty to excise that cancer without delay.
