Manning was found guilty of 19 other criminal counts.

The government pushed for the maximum penalty for the leak, according to the Chicago Tribune. Leaked information included battlefield reports from the Iraq and Afghanistan wars.

The prosecutors argued that U.S. security was harmed by this information being available on WikiLeaks, reports the Washington Post.

The sentencing phase of the trial will begin Wednesday.

The verdict could make it difficult for WikiLeaks to persuade others to share information with the anti-secrecy website.

The Chicago Tribune reported:

"That is going to make it more difficult for people who want to deal with Assange. They are going to be at greater risk and that will put his operation at risk," said Michael Corgan, a professor of international relations at Boston University and former officer in the U.S. Navy.

"It will have a very chilling effect on WikiLeaks," he said ahead of the verdict.
