He incorrectly recounted the history of the F.B.I. and falsely said its director ‘really reports directly to the president of the United States.’

Mr. Trump said that the F.B.I. started reporting to the Justice Department “out of courtesy” after President Richard M. Nixon, but that “there was nothing official, there was nothing from Congress” to cement that relationship.

The F.B.I. was founded in 1908 by Attorney General Charles J. Bonaparte to conduct investigations for the Justice Department, according to the bureau’s website, and Congress expanded its jurisdiction through legislation in the next decade. It officially became the Federal Bureau of Investigation in 1935.

The director “has answered directly to the attorney general since the 1920s,” according to the F.B.I. website, and the Justice Department has guidelines instructing the bureau to communicate with the White House with the approval of the attorney general or other top officials at the Justice Department. Although the director J. Edgar Hoover had close, arguably unethical relationships with six presidents, his successors have tried to distance themselves from the president, according to Douglas M. Charles, a history professor at Pennsylvania State University.

He described savings from health care and tax cuts as a ‘windfall’ for the middle class. The cuts are generally more beneficial to the wealthy.

The original version of the Senate health care bill would have repealed taxes totaling $700 billion over the next decade, with most of the money lining the pockets of the richest Americans, according to the nonpartisan Tax Policy Center.

The latest version retained two taxes from the Affordable Care Act aimed at the wealthy and was “much less regressive,” the center’s Howard Gleckman wrote. While the wealthy would still have seen the largest dollar amount in tax cuts, lower-income households would have gotten a larger cut as a share of after-tax income.

The White House’s tax blueprint — which lacks the details needed for modeling — would provide modest cuts for the middle class, but the rich and businesses have the most to gain.

If it were to contain the elements of Mr. Trump’s campaign pledges, households in the top 1 percent would get an average tax cut of about $270,000, while the middle fifth of Americans would see about $1,900, according to the Tax Policy Center.
