A more thorough explanation:

An omnibus clause is a provision in a contract that covers items, terms, or conditions that were not specifically included in the agreement or provided by law. It is often used in insurance policies and wills.

• Insurance Policy: An automobile insurance policy with an omnibus clause extends coverage to any driver who operates the insured vehicle with the policyholder's consent, even if they are not listed on the policy.
• Last Will and Testament: A residuary clause in a will is an omnibus clause that transfers any leftover assets to a named beneficiary after all other gifts have been made.
• Federal Statute: The federal obstruction of justice statute includes an omnibus clause that criminalizes any attempt to obstruct justice by threatening or using force against a juror, court officer, or magistrate judge.

These examples illustrate how an omnibus clause can be used to cover situations that were not specifically addressed in the original agreement or law. In the case of an insurance policy, the omnibus clause extends coverage to additional drivers who may not have been listed on the policy. In a will, the residuary clause ensures that any leftover assets are distributed to a named beneficiary. And in a federal statute, the omnibus clause broadens the scope of criminal activity that can be prosecuted under the law.
