The 53-year-old judge said in an op-ed that he knows his "tone was sharp, and I said a few things I should not have said" during testimony last week to the Judiciary Committee.
Kavanaugh vociferously denies the allegation.
The report, sent by the White House to the Senate Judiciary Committee last night, was denounced by Democrats as a whitewash that was too narrow in scope and ignored critical witnesses.
But 10 staffers on the Senate Judiciary Committee will have access to the report in hard copy so they can brief senators who have not have time to read it for themselves.
Ford, who testified before the judiciary committee in Washington on September 27, alleges Kavanaugh sexually assaulted her in 1982, when they were high school students.
