NFL general counsel Jeff Pash and former Washington Football Team executive Bruce Allen had a close relationship, according to emails collected during the NFL's workplace misconduct investigation of the Washington franchise, per reports.

The correspondence is among 650,000 emails collected in the NFL's investigation.

The emails helped lead to Jon Gruden's resignation as Las Vegas Raiders coach earlier this week.

The emails between Pash and Allen show Pash reassuring Allen on controversies involving the Washington franchise and discussing league issues and other topics, including politics.
