CULVER CITY, Calif. — A day after offering a forceful denunciation of Donald J. Trump, Hillary Clinton on Friday expressed hope that she was only days away from putting the long-running Democratic nominating fight behind her.

“If all goes well, I will have the great honor as of Tuesday to be the Democratic nominee for president,” she said at a rally featuring a lengthy lineup of well-known actresses, including Sally Field, Debra Messing, Elizabeth Banks, Sophia Bush and Mary Steenburgen.

Mrs. Clinton is expected to secure enough delegates on Tuesday to become the party’s presumptive nominee, probably before the polls close in California, one of the six states with nominating contests that day.

The moment cannot come soon enough for Mrs. Clinton, who has already turned her attention to Mr. Trump, the presumptive Republican nominee, attacking him on a variety of subjects at campaign events, while almost never mentioning her remaining Democratic rival, Senator Bernie Sanders of Vermont.
