Secretary of State Mike Pompeo was asked about the nature of the intelligence that lead to the US airstrike that killed Iranian general Qasem Soleimani.

"There has been much made about this question of intelligence and imminence," Pompeo said. "Anytime a president makes a decision of this magnitude, there are multiple pieces of information that come before us."

Pompeo said that, after looking at the information, "we could see clearly" Soleimani's actions, including "hundreds of thousands of massacres in Syria and enormous destruction of countries like Lebanon and Iraq."

"So if you’re looking for imminence, you need look no further than the days that led up to the strike that was taken against Soleimani," Pompeo said.

Top national security officials continue to defend the Trump administration's claim that it killed Soleimani in response to an impending threat to American lives, but the lack of evidence provided to lawmakers and the public has fueled lingering skepticism about whether the strike was justified.
