A Senate oversight hearing of the Department of Homeland Security became heated as Democrats pushed Secretary Kristi Noem to explain why the Trump administration had not followed through with a Supreme Court order to bring illegal immigrant Kilmar Abrego Garcia back from El Salvador.

Two lawmakers, Sen. Chris Murphy (D-CT) and Sen. Chris Van Hollen (D-MD), went up against Noem during a Senate Appropriations Subcommittee on Homeland Security hearing Thursday, and grew frustrated with the Trump official’s refusal to address their “simple” questions about events that have occurred since the Salvadoran man’s deportation on March 15.
