Twitter reacts to John McCain's line of questioning at Comey's hearing

Toward the end of Former FBI Director James Comey's testimony before the Senate Intelligence Committee on Thursday, Senator John McCain delivered a line of questioning that had Twitter users talking.

McCain spent much of his allotted time asking about the FBI's investigation into Hillary Clinton's email scandal that emerged while she was secretary of state. This drew criticism, as some Twitter users pointed out that allegations of Russian interference in the U.S. election are separate from this particular incident.

He accidentally called Trump "President Comey," as well.

One Twitter user drew attention what seems to be the bored faces of McCain's fellow senators.

McCain has since responded to criticism of his questioning.

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