The day before Rep. Devin Nunes (R-Calif.) revealed that conversations by Trump transition officials may have been inadvertently picked up by U.S. surveillance, he met with the information’s source at the White House, his spokesman said March 27, 2017.

Last week, U.S. Rep. Devin Nunes, a Republican from California, took a trip to the White House that made as big a splash as his home state's recent torrential rains. Even though he is chairman of the House Intelligence Committee that is currently investigating links between Russia and members of Donald Trump's campaign team, Mr. Nunes chose to share intelligence reports with the president before he shared them with members of his committee.

Democrats went ballistic, saying Mr. Nunes had acted improperly, raising serious questions about his ability to lead an independent, bipartisan investigation. Observers with deep ties to the intelligence community said it was unprecedented for someone in the key position Mr. Nunes holds to so brashly share sensitive information with a person who is the object of an inquiry.


Another Californian, U.S. Rep. Adam Schiff, is the ranking Democrat on the intelligence committee. Speaking to reporters in his usual calm ex-prosecutor's voice, Mr. Schiff said, "The chairman will need to decide whether he is the chairman of an independent investigation into conduct which includes allegations of potential coordination between the Trump campaign and the Russians, or if he is going to act as a surrogate of the White House -- because he cannot do both."

In comments outside the West Wing after he met with Mr. Trump, Mr. Nunes said he had told the president that communications from members of his transition team had been inadvertently intercepted by U.S. intelligence agencies. Fox News jumped on this as evidence confirming Mr. Trump's recent tweet that accused President Barack Obama of wiretapping Trump Tower. Despite Fox's quick leap to shill for Mr. Trump, Mr. Nunes' statement actually undercut Mr. Trump's charge by making clear that, not only was the surveillance inadvertent, it was also legal.

Unsurprisingly, Fox, the reliable mouthpiece for the GOP, is reflecting the pervasive denial that is making a lot of Republicans look like quaking little boys whistling past a spooky graveyard. They seem quite desperate to pretend there is nothing scary about the FBI's probe into contacts between Trump surrogates and Russian intelligence operatives at a time when the Russians were hacking their way into the American presidential election to do damage to Hillary Clinton's campaign.

Earlier last week when FBI director James Comey appeared before the intelligence committee, GOP members arrived at the hearing with an orchestrated series of questions focusing, not on the Russian attack on American democracy but on leaks from within government agencies that helped expose connections between Mr. Trump's people and the Russians. They looked more than a little silly chasing this line of inquiry after Mr. Comey dropped a bombshell by acknowledging that his agency is conducting an "active investigation" into the Trump/Russia links.

Mr. Trump apologists are also making themselves look ridiculous by continuing to insist that Paul Manafort, who headed the Trump campaign for a period that included the Republican National Convention, was somehow a marginal figure in Mr. Trump's run for the White House. He was far from peripheral and, according to convention delegates on the platform committee, it was he who engineered the removal of a plank in the platform that called for sending arms to Ukraine in support of that country's fight against Russian military aggression. The story about Mr. Manafort's cozy relationship with Russia blew up again last week with the revelation that Mr. Manafort at one time had a multimillion dollar contract with a Russian oligarch who is part of President Vladimir Putin's inner circle -- a deal in which, according to an Associated Press report, Mr. Manafort promised to provide services that would "greatly benefit the Putin government."

The more Republicans try to protect their president by downplaying the very curious and apparently very frequent contacts between Russians and Trump campaigners, the more it looks as if they are willingly aiding a cover-up. They would do well to stop collaborating and start following the lead of their 2008 presidential nominee, Arizona Sen. John McCain. Mr. McCain is now calling for a select committee to take over the investigation. He sees that as a necessary step toward uncovering the impartial truth.

It will be difficult for other Republicans to argue against Mr. McCain now that Mr. Nunes has so badly compromised his committee's work by trotting off to share secrets with Mr. Trump.
