Hillary Clinton earned more than $5 million in royalties for her 2014 memoir, “Hard Choices,” and roughly $1.5 million delivering speeches last year, according to a personal financial disclosure her campaign released Tuesday evening.

The disclosure came hours after the leading Republican presidential candidate, Donald J. Trump, said he had filed his personal financial disclosure with the Federal Election Commission, as required by law for presidential candidates.

“I filed my P.F.D., which I am proud to say is the largest in the history of the F.E.C.,” Mr. Trump said in a statement Tuesday.

Mrs. Clinton’s campaign used the release of her financial disclosure to seize on Mr. Trump’s refusal to release his tax returns, which he has said he cannot disclose because of a routine audit by the Internal Revenue Service.
