Whistleblower retaliation

1. If the U.S. Constitution is the ultimate law of America and the U.S. Congress passes American laws to protect whistleblowers who report violations of American laws in support of protecting the U.S. Constitution, do the legal protections of American laws, statutes, or regulations apply to any business operating in the U.S., whether linked business entities, funding, or strategic alliances with a foreign adversary, and can the business take any adverse actions against the whistleblower? 2. What are the legal actions a retired servicemember or public servant, who has taken an oath of office, can take to uphold their lifetime commitment to protect the U.S. Constitution from all enemies, foreign and domestic, when the U.S. federal government is compromised by a foreign adversary, not limited to military and economic warfare, and the U.S. Congress has been properly notified?
