WASHINGTON – It’s a witch hunt, a vendetta, the worst presidential harassment in history. That’s what President Donald Trump has shouted for two years about the special counsel’s Russia probe. Now, barring an eleventh-hour surprise, Trump and his allies are starting to see it as something potentially very different: a political opportunity. With Robert Mueller’s findings expected any day, the president has grown increasingly confident the report will produce what he insisted all along – no clear evidence of a conspiracy between Russia and his 2016 campaign.
