...following the radicalism of the French Revolution Henry's views changed as he began to fear a similar fate could befall America and by the late 1790s Henry was in support of the Federalist policies of Washington and Adams. He especially denounced the Virginia and Kentucky Resolutions, which had been secretly written by Jefferson and Madison, and approved by the legislatures of those two states. He warned that civil war was threatened because Virginia, "had quitted the sphere in which she had been placed by the Constitution, and, in daring to pronounce upon the validity of federal laws, had gone out of her jurisdiction in a manner not warranted by any authority, and in the highest degree alarming to every considerate man; that such opposition, on the part of Virginia, to the acts of the general government, must beget their enforcement by military power; that this would probably produce civil war, civil war foreign alliances, and that foreign alliances must necessarily end in subjugation to the powers called in." ... He strongly supported John Marshall and at the urging of Washington stood for and was elected to the Virginia House of Delegates as a Federalist.
Once the Constitution had been ratified, Robert Yates, who was probably Brutus, also said that the debate was over and the Constitution was the supreme law of the land.
That’s not Henry admitting he was wrong in opposing the Constitution. He didn’t recant on any of that. He simply accepted the outcome of the ratification and served honorably under the new system.
Brutal irony in all of that. Henry tried to warn them, but no, they had to have their new fangled system. Then almost immediately they scrambled around trying to deal with the damage they'd wrought,and there was Henry, properly interpreting the system THEY created.
