The CIA source also mentioned that Mr. Comey has been under a lot of pressure to slow down the investigation in order to provide the Trump’s administration enough time to devise a way out of this impossible situation. A number of steps were taken by the Trump’s White House to achieve the outcome Donald Trump would like to have according to the source

1. Chief of staff Reince Priebus attempted very early on, well before Mr. Comey revealed to Congress (and the nation) there is an investigation into Trump’s collusion with Russia, to curve any attempt by FBI to begin or continue any investigation. A number of people – behind the scenes – tried to influence Mr. Comey to drop the investigation altogether. Although it’s impossible to know whether Mr. Comey has been “bought”, it is now safe to conclude that it has become harder for the Trump’s administration to put an end to the investigation or for Mr. Comey to simply sweep it under the rug. Too many interested parties, especially investigative reporters, the Democrat Party and even those whose loyalty align with the country instead of a political Party have now shown interest.
2. Chairman Devin Nunes was not appointed to lead the House Intelligence Committee on Trump’s collusion with Russia by accident. Any Representative loyal to the country would have already foreseen the conflict of interest, given that Mr. Nunes participated in Trump’s transition team after Mr. Trump won the presidential election. Mr. Nunes himself would have voluntarily declined to lead such an important matter but it was a calculated move to have someone who is very friendly to the Trump’s White House to be in control of an investigation which outcome, by most analysis, will be damaging to Mr. Trump. For instance, at the slightest whiff of something unflattering about Trump, Mr. Nunes rushed to the White House to pass the information to Donald Trump, hardly someone fit to be part of an investigation let alone be the chairman of such investigation. Once caught as Mr. Nunes was, anyone who is serious about getting to the bottom of this important matter would have simply recused himself but Mr. Nunes fought tooth and nails to keep his position as lead of the investigation. Despite having in the end decided to step aside, which might be construed as a victory to the Democrats, Mr. Nunes has already done enough damage to the investigation; to continue with the process would generate very little result, if any. Besides, Mr. Nunes still remains the chairman of the Intelligence Committee and has even suggested that his replacement is temporary; translation, he is now in an even better position to funnel information – about the investigation – to the White House without being held accountable, without being scrutinized.
3. Paul Ryan, Republican Speaker of the House, appointed Nunes as Chair of the committee both as a favor to the White House but also as a bargaining chip to obtain concessions from the White House. Mr. Ryan is privy of the information regarding Nunes’ participation in Trump’s transition team. Paul Ryan didn’t have to be a genius to figure out the implication of having that same individual (Devin Nunes) leading an investigation on someone (Trump) he served. But Paul Ryan put obtaining concessions from the White House above loyalty to the country. Mr. Ryan’s calculation didn’t quite pay off but he remains hopeful that he still has a chance to “turn Trump around”; although more cautious than before, Mr. Ryan continues to do favor to the White House by appointing Mike Conaway to lead the investigation. Besides being a Republican, Mr. Conaway even questioned the premise that Mr. Trump colluded with Russia, hardly a good fit for the investigation into Trump’s collusion with Russia. Mr. Conaway is as unfit as Devin Nunes was.
