In the chamber where he was impeached, President Donald Trump on Tuesday delivered his third State of the Union address, boasting of his record on jobs and warning against Democratic policy proposals. The speech came in the thick of the president's 2020 reelection campaign, and one day before he is expected to be acquitted by the Senate on impeachment charges brought by the Democratic-led House . The ceremonial address to the joint session of Congress resembled a campaign speech, with the president claiming to have created "the greatest economy that we've had in our history," pledging to protect Social Security and warning against Democratic policy proposals. Republicans led a chant of "four more years" at the start. The president did not mention impeachment. Among those in attendance was Venezuelan opposition leader Juan Guaido, whom the Trump administration has supported in his efforts to topple President Nicolas Maduro, the country's socialist leader. Notably absent from the speech was a slate of high-profile Democrats, including the progressive freshmen Reps. Alexandria Ocasio-Cortez of New York and Ayanna Pressley of Massachusetts. Here are the night's top moments.

Trump doesn't shake Pelosi's hand, she rips up his speech

The night began and ended with dramatic acts of partisanship. House Speaker Nancy Pelosi sought to shake the president's hand after Trump handed her what appeared to be a copy of his remarks. But Trump did not shake her hand. At the end of the speech, Pelosi ripped up the papers and cast them aside. Asked why she did so, Pelosi explained to reporters afterwards: "It was the courteous thing to do, considering the alternative." She didn't elaborate. Pelosi and Trump have tangled over politics and matters of temperament, with tensions rising particularly high during the impeachment process. But the Pelosi-Trump feud began much earlier. In May, even as she resisted calls for impeachment, Pelosi suggested that Trump's staff should stage "an intervention." CNBC TWEET

Limbaugh awarded Presidential Medal of Freedom

The president awarded the conservative radio host Rush Limbaugh America's highest civilian honor, with the first lady affixing the honor herself. Limbaugh, a close ally of the president, announced on his radio program on Monday that he has advanced lung cancer. "This is not good news," Trump said, referring to the diagnosis. "But what is good news is that he is the greatest fighter and winner that you will ever meet. Rush Limbaugh: Thank you for your decades of tireless devotion to our country." Trump has also awarded Presidential Medals of Freedom to former Sen. Orrin Hatch, the late Justice Antonin Scalia, long-dead music legend Elvis Presley and star golfer Tiger Woods.

Trump celebrates Guaido, Venezuela's 'legitimate' leader

One of the president's special guests on Tuesday was Venezuelan opposition leader Juan Guaido, who is pushing to overthrow Nicolas Maduro, the country's president. "Maduro is an illegitimate ruler, a tyrant who brutalizes his people. But Maduro's grip of tyranny will be smashed and broken," Trump said. "Here this evening is a man who carries with him the hopes, dreams and aspirations of all Venezuelans. Joining us in the gallery is the true and legitimate president of Venezuela, Juan Guaido." Bloomberg News reported in December that Trump was beginning to lose confidence in Guaido's ability to oust Maduro. The White House has been upping its pressure campaign on Maduro in recent weeks. The administration last month announced new sanctions on more than a dozen aircraft operated by the country's state-owned oil company that transport senior members of the Maduro regime.
