President Barack Obama seems critical of FBI Director James Comey for sending a letter to Congress informing it that the investigation of Hillary Clinton’s private email server remains open.

In an interview with Now This News, Obama explained that he tried to avoid “meddling” in the ongoing investigations and was careful not to name Comey specifically.

“I do think that there is a norm that when there are investigations, we don’t operate on innuendo,” Obama said. “We don’t operate on incomplete information. We don’t operate on leaks. We operate based on concrete decisions that are made.”

Obama defended Clinton, arguing that nothing had been found to incriminate her so far.

“When this was investigated thoroughly the last time, the conclusion of the FBI, the conclusion of the Justice Department, the conclusion of repeated Congressional investigations was that, you know, she made some mistakes but that there wasn’t anything there that was, you know, prosecutable,” Obama said.
