WASHINGTON (AP) — Attorney General Loretta Lynch says she won’t overrule the findings of an FBI-led investigation into Hillary Clinton’s private email server.

She also acknowledged that an impromptu meeting this week with Bill Clinton that caused a political firestorm is not something she would do again.

Lynch addressed her part in the investigation at a conference in Colorado.

She said she understood that her private meeting with Clinton aboard her plane in Phoenix “cast a shadow” over the public perception of the neutrality of the investigation.

Her pledge seems aimed at tamping down criticism that the investigation is politically tainted.
