The special counsel's investigation into possible collusion found that members of the Trump campaign knew they would benefit from Russia's illegal actions to influence the election, but didn't take criminal steps to help, Robert Mueller's report said.
"Although the investigation established that the Russian government perceived it would benefit from a Trump presidency and worked to secure that outcome, and that the campaign expected it would benefit electorally from information stolen and released through Russian efforts, the investigation did not establish that members of the Trump campaign conspired or coordinated with the Russian government in the election interference activities," the report said.
Mueller specifically said Trump's presidential campaign "showed interest" in WikiLeaks' releases of emails that the Russians stole from the Democrats to hurt his opponent Hillary Clinton.
Barr noted earlier Thursday that "publication of these types of materials would not be criminal unless the publisher also participated in the underlying hacking conspiracy."
