CNN’s Jeremy Herb caught up with Senator Susan Collins, a crucial swing vote, after the senators briefing on the FBI report.

She did not indicate how she would vote on Kavanaugh’s confirmation but said of the FBI report “it appears to be a very thorough investigation.”

She added she would read the report in full later today.

CNN's Manu Raju reports that this comment from Collins is "hugely significant" as it suggests that she is satisfied with how this investigation went, making it clear she's siding with the Republicans on that key question about whether or not this investigation was done thoroughly and completely.

"She believes it has," Raju just said. "Now, what does that mean for her vote? We don't have final answer on that yet."
