Another repost of my comment but this sums it up. I'm only reposting it to reply directly to people asking. Bongino has talked about all of this.

He went to Washington and told them that they were getting US soldiers killed trying to play war general from DC instead of letting the generals do it.

He was against the Iran Deal.

He wanted to audit the dark money in the federal budget.

He warned that the surveillance state had too much power and could be misused by presidents.
