President-elect Donald J. Trump delivered a sprawling address on Sunday that he called a “small preview of the common-sense revolution” his administration will bring, pledging to slam shut the nation’s borders, end federal regulations, lower taxes, prosecute his rivals, “stop woke” and “end the transgender lunacy.”

In a 90-minute speech at a conservative conference in Phoenix, Mr. Trump offered a triumphant view of his election victory in which he described his liberal adversaries as “befuddled” and promised that a new “golden age in America” had begun.

“We will end the occupation, and Jan. 20 will truly be liberation day in America,” Mr. Trump told thousands of people at AmericaFest, a four-day conference run by the conservative group Turning Point USA.

The president-elect’s speech was a familiar mash-up of false assertions, self-praise, fierce attacks on his adversaries and promises about how his return to power would change the country for the better.

As he often does, Mr. Trump spent the most time on immigration and the border. He repeated his claim, without evidence, that other countries were emptying their “insane asylums” and prisons into the United States. And he vowed to purge the country of people who have entered illegally.

“On my first day, I will sign a historic slate of executive orders to close our border,” he said to huge applause from the audience. “On that same day, we will begin the largest deportation operation in American history.”
