But another issue overshadowed the visit. When reporters tried to question the president about why he gave his son Hunter a far-reaching pardon after repeatedly saying he would not do so, Biden tried to brush aside the questions. He gestured toward Lourenco and laughed, declaring, "Welcome to America."

Biden saluted Lourenco for his efforts to bolster stronger U.S. relations, declared that Africa and its booming youth population would shape the world's future and even indulged his love of trains by championing a major railway project that his administration says could change the way the entire continent does business.

Some takeaways from the president's visit:

(Don't) meet the press

Biden offered the joke about America before his meeting with Lourenco, and he answered a question on Tuesday about the political situation in South Korea, saying only that he'd not been briefed -- something that was rectified moments later when advisers filled him in on what was happening as the motorcade sped away from a site where he'd given a speech.

Other than that, Biden went the entire trip, which began Sunday night and included two brief stopovers in Cape Verde in addition to Angola, dodging reporters. He did similar during last month's six-day visit to South America.

Biden's press secretary tried to explain the pardon decision

Since Biden announced his pardon decision shortly before climbing aboard Air Force One bound for Africa, it fell to White House press secretary Karine Jean-Pierre to spend nearly half an hour offering long and awkward answers to uncomfortable questions aboard the aircraft hours later.

Biden said in a statement explaining the pardon that, while he believed in the justice system, he also felt that politics had infected the cases against his son and "enough was enough." Jean-Pierre maintained that he wasn't trying to have it both ways.

"I don't think it's a contradiction," she said. "Two things could be true. You can believe in the Department of Justice system, and you could also believe that the process was infected politically."

She also bristled when it was suggested that such complaints about the Department of Justice smacked of President-elect Donald Trump's promises to dismantle the "deep state" of federal bureaucrats that he's said for years are out to unfairly undermine him and fellow top Republicans.

'All in on Africa' -- with time running out

During his meeting with Lourenco at the presidential palace, Biden said, "The United States is all in on Africa," and extolled how strong Angolan relations were with Washington.

His administration has invested billions in Angola, with the centerpiece being promoting the Lobito Corridor, a vast project to revitalize supply chains by refurbishing 800 miles (1,300 kilometers) of train lines in Angola, Zambia and Congo.

Given where Angola was barely a generation ago, the alliance is in many ways remarkable.

An oil-rich nation on Africa's southwest coast, Angola achieved independence from Portugal in 1975, but spent subsequent years embroiled in civil war, which often featured proxy fighting between U.S.-backed forces and those allied with the Soviet Union. Even today, the country's red and black flag features a yellow machete and half-cog, an insignia resembling the Soviet hammer and sickle.

But Biden leaves office on Jan. 20, and Lourenco, like many leaders of African nations, has already begun suggesting that he's looking toward a Trump-dominated future.

Biden administration officials say they're hopeful Trump and top Republicans will continue a business-friendly approach to investing in Africa that includes continuing to support the Lobito Corridor.

Now the Africa policy will be up to Trump

Biden lauded Lourenco for helping boost his country's relationship with the United States, and he said the youth of Africa would change the world. He also visited the country's national slavery museum, stressing how Angola and the United States -- which were once linked by the horrors of enslaved human beings, now could increasingly be linked by economic opportunity.

But if Biden came to Angola hoping to cement his foreign policy legacy in this country and throughout Africa, it will actually fall to Trump -- the man he beat in the 2020 election and spent much of 2024 running against before bowing out of the race in July -- to see it through.
