"Maybe going forward I shouldn't stay up late watching the Diamondbacks night games", McCain later conceded in a statement.
Instead, McCain flummoxed Comey with a question about why "the investigation of anything former Secretary Clinton had to do with the campaign is over and we don't have to worry about it anymore?"
He said he felt Lynch was trying to align the FBI's description of its investigation with Clinton's messaging in a bid to help her with the 2016 presidential election.

Comey testified at the Senate intelligence committee on the government's investigation into Russian meddling in the USA election and his firing by President Donald Trump.

The dovish comments from Mr Draghi weighed on the euro, lifting the dollar higher, which dampened demand for the precious metal. Platinum climbed 0.6 percent to $947.80 per ounce, and silver rose 0.5 percent to $17.63.
Speaking for almost six minutes, McCain asked why Comey was able to state that the investigation into Hillary Clinton's private email server did not need to be pursued but that he could not say the same of the probe into President Donald Trump's administration.
Comey alleged on Thursday that Lynch specifically told him not to refer to the email probe as an "investigation", but rather to describe it as a "matter". After Clinton and Lynch met as their planes were on the same tarmac, Comey said he decided he had to "protect the credibility of the investigation". Comey said the Russian investigation is ongoing as far as he knows.
"I get the sense from Twitter that my line of questioning today went over people's heads".
Arizona Senator John McCain was widely criticized for his questioning of James Comey, for questions that at times seemed a little fuzzy.
The team also retweeted McCain's statement about being exhausted, with a "shrug" emoji.
