WASHINGTON — Andrew G. McCabe, the former F.B.I. deputy director and a frequent target of President Trump’s scorn, was fired Friday after Attorney General Jeff Sessions rejected an appeal that would have let him retire this weekend.

Mr. McCabe promptly declared that his firing, and Mr. Trump’s persistent needling, were intended to undermine the special counsel’s investigation in which he is a potential witness.

Mr. McCabe is accused in a yet-to-be-released internal report of failing to be forthcoming about a conversation he authorized between F.B.I. officials and a journalist.

In a statement released late Friday, Mr. Sessions said that Mr. McCabe had shown a lack of candor under oath on multiple occasions.
