Sen. John McCain said that his decision to stay up late watching an Arizona Diamondbacks baseball game contributed to his confusing series of questions to former FBI Director James Comey on Thursday.

"I get the sense from Twitter that my line of questioning today went over people's heads. Maybe going forward I shouldn't stay up late watching the Diamondbacks night games," the Arizona Republican said in a statement.

Twitter slammed McCain after his questions during the Senate Intelligence Committee hearing, two of which focused on the 2016 FBI investigation into Hillary Clinton's emails and the 2017 investigation into Russian meddling in the presidential election. Comey appeared confused by McCain's questions, and McCain himself looked frustrated as he asked them.

"In the case of Hillary Clinton, you made the statement that there wasn't sufficient evidence to bring a suit against her, although it had been very careless in their behavior, but you did reach a conclusion in that case that it was not necessary to further pursue her," McCain began during his questioning. "Yet at the same time, in the case of Mr. [Trump], you said that there was not enough information to make a conclusion. Tell me the difference between your conclusion as far as former Secretary Clinton is concerned, and Mr. Trump."

In his follow-up statement, McCain said he was trying to ask Comey if he "believes that any of his interactions with the president rise to the level of obstruction of justice."

"In the case of Secretary Clinton's emails, Mr. Comey was willing to step beyond his role as an investigator and state his belief about what ‘no reasonable prosecutor' would conclude about the evidence. I wanted Mr. Comey to apply the same approach to the key question surrounding his interactions with President Trump," McCain explained.

Twitter announced that McCain's questions to Comey were the most-tweeted moment of the nearly 3-hour long hearing.

The Diamondbacks replied to McCain's statement by retweeting it with a shrug:
