That said, laws generally permit some leeway to the executive to set spending priorities/focus. It can be pretty limited since Congress tends to specify what department and sometimes program money must be spent on, but it still it allows for things like deciding you're going to prosecute more drug dealers even though they're long shot cases rather than easier to win fraud causes. This is done at all levels of government.
Shifting spending priorities as the law allows, though, is rather different from actively breaking the law.
Back the Blue apparently includes demonizing their daily effort to process asylees, rescue families in danger, and arrest gang-affiliated criminals, all while forgetting that crossing the border illegally is a civil offense akin to a speeding ticket. But now that we are a physical threat to their safety, we supposedly have a secure border.
