Senate Intelligence Committee says it has wrapped up its investigation into James Comey's firing

Senate Intelligence Committee chairman Richard Burr said at a Wednesday press conference that his committee "has reached a logical end" with its investigation of former FBI Director James Comey's firing.

Burr, a Republican senator from North Carolina, mentioned the memos Comey kept of his meetings with Trump, saying they were "hotly debated."

He went on to say that the committee's
"involvement with this issue has reached a logical end as it relates to the Russia investigation."

But he clarified that the committee has not "closed" this issue, but rather has "exhausted every person that we can talk to to get information that is pertinent" to its investigation into Russian interference in the 2016 presidential election. Trump's firing of Comey became a subject of the committee's investigation because Comey was overseeing an FBI investigation into into whether any members of Trump's orbit colluded with Russian officials in the campaign.

"Questions that you might have surrounding Comey's firing are better answered by the general counsel or by the Justice Department, not by the select committee of intelligence in the United State Senate," Burr said.

Trump first cited Comey's handling of the investigation into former Secretary of State Hillary Clinton's use of private email server as a reason for his firing, but then later said he was fired because of the FBI's Russia investigation. Deputy Attorney General Rod Rosenstein soon after appointed former FBI Director Robert Mueller to be special counsel overseeing that investigation.

Comey testified before Burr's committee in June to discuss his firing and the detailed memos he kept on his interactions with Trump, which were disseminated to the media in the days that followed his firing. Some said Trump's firing of Comey amounted to obstruction of justice, and Mueller's investigation would later broaden to include a probe into whether Trump did obstruct justice by firing Comey.

Burr later added that the committee "continues to look into all evidence" related to potential collusion between campaigns and Russian officials who sought to meddle in the 2016 election.
