Hillary Clinton joked Monday that she never had to tell former President Obama not to withhold aid from allies in order to secure damaging information on political opponents, responding to reports that Secretary of State Mike Pompeo was on the call between President Trump and the Ukrainian president at the center of the impeachment inquiry launched by House Democrats.

“How many times when you were secretary of State did you have to say to Barack Obama, ‘You can’t extort foreign countries to get dirt on your political enemies’?” Stephen Colbert, host of “The Late Show,” asked Clinton.

{mosads}”Yeah, that never happened,” Clinton responded in an advance clip put out by the show on Twitter. “No.”

Colbert followed up by asking Clinton what the role of the secretary of State should be in those situations.

“The secretary of State’s job is to make sure that he knows, number one, what the president is going to say on those calls,” said Clinton, painting a picture of a coordinated effort and shared talking points put together before the president ever calls a foreign leader.

“Because you’ve got a president who doesn’t listen to anybody and doesn’t follow instructions whatsoever, I’m not sure they [haven’t] given up on trying to give him any sort of preparation,” she added.

The Wall Street Journal reported Monday that Pompeo was on the July 25 call in which Trump pressed Ukrainian President Volodymyr Zelensky to investigate former Vice President Joe Biden and his son Hunter Biden. The call came just days after Trump delayed the delivery of hundreds of millions of dollars in aid to Ukraine.

The Hill has reached out to the State Department and White House about Pompeo’s participation.

Democrats officially launched an impeachment inquiry into Trump last week, saying his actions show he was trying it use the powers of the presidency for political gain.
