Biden has been President since Jan 20, 2021.
In that time, Congress has appropriated trillions of dollars in new Federal Spending
Biden has had 3 years, and trillions of dollars to act on Border Security, but he has chosen not to act. Biden's Open Border policy is a policy of Biden's choosing.
Biden is not acting in good faith. If Biden wants suppplemental appropriations, he needs to Secure the Border, first. Action, not words.
