President-elect Donald Trump. Screenshot via CBS News President-elect Donald Trump, in his first television interview since beating Hillary Clinton in a historic election, apparently no longer thinks Clinton is "crooked."

Trump immortalized the "Crooked Hillary" moniker he used to describe his Democratic opponent over more than a year of campaigning. He now says Clinton is a "very strong and very smart" woman.

Trump made the comments during an interview with CBS' "60 Minutes," set to air Sunday. He talked about the concession phone call he received from Clinton in the early hours of Wednesday morning, after it became clear that he would win the White House:

"It was a lovely call and it was a tough call for her," Trump said. "She couldn't have been nicer. She just said, 'Congratulations, Donald. Well done.'"

During a heated election campaign, Trump attached several different nicknames to Clinton, including "Heartless Hillary," "Unstable Hillary Clinton," and "Lyin' Hillary."At the end of the final debate in October, Trump called Clinton a "nasty woman."

The real-estate mogul had glowing praise for former president Bill Clinton as well, saying "He couldn't have been more gracious," in a phone call the two men had after Trump won. The Trump campaign targeted Bill at the height of the election — reintroducing decades-old sexual misconduct allegations against him to damage Hillary.

After his conversation with the former president, Trump called him "Very, very, really very nice."

Since the election, Trump appeared to be trying to polish up his image. After tweeting on Thursday that the thousands of anti-Trump protesters demonstrating nationwide were professionals "incited by the media," he followed that up hours later in a toned-down tweet: "Love the fact that the small groups of protesters last night have passion for our great country."

Supporters may not be pleased with all of the changes, however. Appearing to defy a campaign goal to "drain the swamp" of cronyism in Washington, Trump stacked his White House transition team with Washington lobbyists and insiders.
