The president can enforce a law passed by Congress through the executive branch, which includes various federal agencies responsible for implementing and regulating the law. The president may issue executive orders or directives to guide these agencies in their enforcement actions. Additionally, the president can propose budgets and allocate resources to ensure effective enforcement, as well as appoint key officials to lead the relevant agencies. Ultimately, the president's role is to ensure compliance with Federal Laws and uphold the rule of law.
the congress can veto a law the president passed
The president has federal agencies and the armed forces to enforce policies and laws. However Congress has the purse strings to fund this.
The President
The Supreme Court can declare a law passed by Congress to be unconstitutional and therefore null and void. The President can veto laws by Congress and fail to enforce them if his party has an impeachment-proof minority in Senate.
Congress cannot veto a law. Any law must be written and passed by Congress in the first place. The president can then veto it. Congress can override the veto with a 2/3 majority. After a law is passed, the Supreme Court can strike it down if they declare the law unconstitutional.
They can try to override the veto.
Force bill
No- after a law has been passed, the President can not do anything to change it. He can sometimes get away with ordering the justice department not to enforce a law he does not like as the current president does with parts of the immigration laws and the defense of marriage act. The president can veto a proposed law (bill) and send it back to Congress to either pass it over his veto via a 2/3 majority or else re-work it into a bill he will sign.
