Call it the scandal that will not die. Or, more accurately, the scandalmongering that will not die. In the last few weeks, there has been a spate of new assertions that presidential candidate Donald Trump and the Trump campaign did, in fact, collude with Russia to fix the 2016 election. No matter that special counsel Robert Mueller and his team of prosecutors, an aggressive bunch with a big budget and all the powers of U.S. law enforcement, investigated the collusion allegation for years and failed to establish that it ever happened.
