The facts, had they surfaced, might have devastated the Trump campaign: Mr. Trump’s future national security adviser was under investigation, as was his campaign chairman. One adviser appeared to have Russian intelligence contacts. Another was suspected of being a Russian agent himself. 
  
 In the Clinton case, Mr. Comey has said he erred on the side of transparency. But in the face of questions from Congress about the Trump campaign, the F.B.I. declined to tip its hand. And when The New York Times tried to assess the state of the investigation in October 2016, law enforcement officials cautioned against drawing any conclusions, resulting in a story that significantly played down the case. 
  
 Mr. Comey has said it is unfair to compare the Clinton case, which was winding down in the summer of 2016, with the Russia case, which was in its earliest stages. He said he did not make political considerations about who would benefit from each decision. 
  
 But underpinning both cases was one political calculation: that Mrs. Clinton would win and Mr. Trump would lose. Agents feared being seen as withholding information or going too easy on her. And they worried that any overt actions against Mr. Trump’s campaign would only reinforce his claims that the election was being rigged against him. 
  
 The F.B.I. now faces those very criticisms and more. Mr. Trump says he is the victim of a politicized F.B.I. He says senior agents tried to rig the election by declining to prosecute Mrs. Clinton, then drummed up the Russia investigation to undermine his presidency. He has declared that a deeply rooted cabal — including his own appointees — is working against him. 
  
 That argument is the heart of Mr. Trump’s grievances with the federal investigation. In the face of bipartisan support for the special counsel, Robert S. Mueller III, Mr. Trump and his allies have made a priority of questioning how the investigation was conducted in late 2016 and trying to discredit it. 
  
 “It’s a witch hunt,” Mr. Trump said last month on Fox News. “And they know that, and I’ve been able to message it.” ||||| Tweet with a location

It's something Trump has said would be "bigger than Watergate" and the "all time biggest political scandal" ever if it pans out to be true. What he's referring to: a report in the New York Times this week that the FBI planted an informant to spy on his campaign during the 2016 election. Politico notes the president and his allies are now using this report to sow doubt about the validity of Robert Mueller's probe into Russian interference in the election, as well as possible ties between Russia and Trump associates. "This has never been done before and by any means necessary, they are out to frame Donald Trump for crimes he didn't commit," Trump quote-tweeted Fox Business Network anchor David Asman Friday morning. "Really bad stuff!" he added as his own take. More from around the internet: The original Times story notes that current and former FBI officials have said "at least one government informant" met up multiple times with Trump associates Carter Page and George Papadopoulos, which has led some in Trump's camp to cry attempted entrapment. Still, sources in the DOJ and FBI say agents weren't nearly as aggressive as they could have been. The article also notes the Russia investigation's initial code name: Crossfire Hurricane, taken from the lyrics of the Rolling Stones song "Jumpin' Jack Flash." Earlier this month, the Washington Post noted a "rare moment of alignment" between Trump and the Justice Department he's been battling with: an agreement not to turn over sensitive DOJ info to House Intelligence Committee Chair Devin Nunes for fear of outing a "top-secret intelligence source" and putting lives at risk. Now that it's been revealed that source spilled info to Robert Mueller, some administration officials fear Trump may soon reverse course and give Nunes what he wants.
