Some excerpts from fbi history leading to a question and with sauce:

"The chain of events was set in motion in 1906, when Roosevelt appointed a likeminded reformer named Charles Bonaparte as his second Attorney General. The grandnephew of the infamous French emperor, Bonaparte was a noted civic reformer. He met Roosevelt in 1892 when they both spoke at a reform meeting in Baltimore. Roosevelt, then with the Commission, talked with pride about his insistence that Border Patrol applicants pass marksmanship tests, with the most accurate getting the jobs. Following him on the program, Bonaparte countered, tongue in cheek, that target shooting was not the way to get the best men. “ Roosevelt should have had the men shoot at each other, and given the jobs to the survivors.” Roosevelt soon grew to trust this short, stocky, balding man from Baltimore and appointed Bonaparte to a series of posts during his presidency.

Soon after becoming the nation’s top lawman, Bonaparte learned that his hands were largely tied in tackling the rising tide of crime and corruption. He had no squad of investigators to call his own except for one or two special agents and other investigators who carried out specific assignments on his behalf. They included a force of examiners trained as accountants who reviewed the financial transactions of the federal courts and some civil rights investigators. By 1907, when he wanted to send an investigator out to gather the facts or to help a U.S. Attorney build a case, he was usually borrowing operatives from the Secret Service. These men were well trained, dedicated—and expensive. And they reported not to the Attorney General, but to the Chief of the Secret Service. This situation frustrated Bonaparte, who had little control over his own investigations.

Bonaparte made the problem known to Congress, which wondered why he was even renting Secret Service investigators at all when there was no specific provision in the law for it. In a complicated, political showdown with Congress, involving what lawmakers charged was Roosevelt’s grab for executive power, Congress banned the loan of Secret Service operatives to any federal department in May 1908.

Now Bonaparte had no choice, ironically, but to create his own force of investigators, and that’s exactly what he did in the coming weeks, apparently with Roosevelt’s blessing. In late June, the Attorney General quietly hired nine of the Secret Service investigators he had borrowed before and brought them together with another 25 of his own to form a special agent force. On July 26, 1908, Bonaparte ordered Department of Justice attorneys to refer most investigative matters to his Chief Examiner, Stanley W. Finch, for handling by one of these 34 agents. The new force had its mission—to conduct investigations for the Department of Justice—so that date is celebrated as the official birth of the FBI."

Also from the fbi's own literature: "With Congress raising no objections to this new unnamed force as it returned from its summer vacation, Bonaparte kept a hold on its work for the next seven months before stepping down with his retiring president in early March 1909. A few days later, on March 16, Bonaparte’s successor, Attorney General George W. Wickersham, gave this band of agents their first name—the Bureau of Investigation. It stuck."

Congress had nothing to do with it and didn't even - apparently - question it or debate it or have any Congressional Hearings on this new "force" and since then have simply dealt with it as a "fait accompli."

So the fbi was actually created by the Attorney General in 1908, it had nothing to do with Congress and in fact Congress didn't care and it is under the authority of the DOJ. If it is found that the corruption and treason and sedition now evident from Comey on down, what if it is now deemed that the fbi is no longer necessary and the DOJ and the Attorney General decide to shut it down and move the newly vetted loyal-to-America and the Constitution staff to other agencies with "fewer" problems than the fbi while releasing or jailing the rest?

Would seem to be a good idea. Would save a lot of money.
