Stephen Colbert Asks Hillary Clinton 'Is It Time to…Lock Him Up?' Over Donald Trump's Ukraine Call

Former Secretary of State Hillary Clinton laughed as the audience on The Late Show with Stephen Colbert chanted "lock him up" in reference to President Donald Trump.

The late night host cheekily asked Clinton: "Is it time to, dare I say, lock him up, lock him up?" while pumping his fist—a chant the audience quickly joined in with.

Clinton also laughed off the idea that she would need to tell former President Barack Obama not to extort a foreign leader, but mused that Trump's staff might have stopped trying because "they don't know what he's going to say."

In an appearance on The Late Show alongside her daughter Chelsea Clinton, in which the pair promoted their new tome The Book of Gutsy Women, Hillary Clinton discussed the impeachment inquiry into Trump, following whistleblower allegations that he asked Ukrainian President Volodymyr Zelensky to investigate potential political rival Joe Biden.

Following the claim that Trump's Secretary of State Mike Pompeo was also on the Ukraine call, Colbert asked Hillary Clinton about her experience as secretary of state and whether she had ever had to speak with Obama about his conduct in such a way.

"How many times when you were Secretary of State with President Barack Obama did you say, 'You can't extort foreign countries to get dirt on your political enemies?'" Colbert asked Hillary Clinton.

She laughed at his question, answering: "Yeah that never happened, no."

"Because you've got a president who doesn't listen to anybody and doesn't follow instructions whatsoever, I don't know if they've even given up on trying these sorts of preparation because they don't know what he's going to say," she pondered of the president's cabinet.

The late night host also cheekily asked the former presidential hopeful whether she believed that they should "lock him up," playing on Trump's campaign push that saw crowds of his supporters chanting that Hillary Clinton should be locked up over her use of a private email server during her time as secretary of state.

Unsurprisingly, Hillary Clinton confirmed that she supported the impeachment inquiry, while Chelsea Clinton commented that calls to "lock her up" had at times left her concerned for her mother's safety.

"I believe strongly that this particular incident has had such a huge impact," Hillary Clinton said of the Ukraine allegations. "To see him in the office of the president putting his own personal and political interest ahead of the national security of our country just pierced through whatever confusion or denial people had."

The president has dismissed the whistleblower allegations as a witch hunt and has insisted that he did nothing wrong during his conversation with Zelensky, with the White House releasing a summary transcript of the call last week. However, Trump's critics have commented that even the summary transcript shows the president discussing Biden with a foreign leader and have question whether this in itself is inappropriate.
