Lindsey Graham says James Comey 'needs to be held accountable' if he interfered in the election over 'fake information'.

The South Carolina Senator spoke to Dana Bash on CNN's State of the Union about reports Comey acted on Russian intelligence concerning the Hillary Clinton email scandal, even though he knew the information was false.

'I'm not so sure the email that Comey relied upon was fake, but I can tell you this, he never briefed the Congress, the Judiciary Committee, about any fake email,' Graham said.

'What he told the intelligence committee about this email, he never suggested it was fake, so if he intervened in the election based on fake information generated by the Russians, that was incredibly incompetent.

Lindsey Graham says James Comey 'needs to be held accountable' if he interfered in the election over 'fake information'

'So I don't really know who to believe anymore.'

The emails Comey allegedly knew to be fake were made by the Russians to look as though they were between then-Democratic National Committee Chair Debbie Wasserman Schultz and political operative Leonard Benardo, which implied then-Attorney General Loretta Lynch would make the FBI's investigation of Hillary Clinton go away.

Comey feared the Russians would release the information and it would be impossible to prove false without burning other intelligence methods, sources told the outlet.

He was also concerned it would be released if Lynch announced Clinton had been cleared, which would again discredit the entire investigation.

Comey reportedly emails that compromised then-Attorney General Loretta Lynch in relation to the Hillary Clinton email scandal were fake, but acted anyway. He is pictured in April 2016

As a result, without consulting Lynch, Comey publicly announced the end of the investigation last summer and said Clinton had been 'extremely careless'.

Wasserman Schultz and Benardo both told the Washington Post they do not know each other, and have never sent emails to one another.

They also said they were not once investigated by the FBI over the incident.

'That, to me, is a stunning story,' Graham said on Sunday.

'The FBI Director knew the information he relied upon to jump into the 2016 election was fake... he basically took over the Department of Justice's job based on a fake email from the Russians.

'He never told us it was fake, so he needs to be held accountable. I want to get to the bottom of it. I want to see the email.'
