In what is described as a “hard” retaliation, Iran’s government has fired a series of ballistic missiles.
These missiles are aimed at military bases in Iraq housing U.S. troops.
This retaliation comes days after Trump ordered an airstrike that killed a top Iranian general.
It also comes as Trump is in the middle of facing a likely impeachment trial in the Senate.
Both Mike Pompeo and Mark Esper arrived at the White House on Tuesday evening after the attack.
