U.S. Attorney General William Barr has explained the process for redacting the special counsel's report on Russian interference in the 2016 U.S. elections -- saying no material was redacted on the basis of President Donald Trump invoking "executive privilege."

Barr said Special Counsel Robert Mueller's investigation found evidence that the Russian state did try to interfere with the 2016 U.S. presidential election.

But Barr said the investigation did not find any evidence that Trump or his campaign team colluded with the Russian efforts.

Barr said Mueller's report did not present any evidence that Trump attempted to obstruct justice during the investigation into Russian attempts to interfere in the 2016 U.S. presidential election.
