Often Quiet On Wars, Congress Challenges White House Over Yemen

President Trump sent a largely unnoticed letter to Congress last week saying the U.S. is engaged in at least seven separate military conflicts.

In most cases, though not all, Trump and his two immediate White House predecessors launched these U.S. military actions without explicit approval from Congress.

"Congress has been silent while the executive branch continues to assert its power," said Rep. Ro Khanna (D-Calif.).

But something is stirring in Congress. There's growing sentiment to force the president to end U.S. involvement in a war.

In this case, it's Yemen.

The killing of Saudi Arabian journalist Jamal Khashoggi, by Saudi officials, set off a chain of events that's led Congress to become much more vocal in opposing U.S. military aid to Saudi Arabia, which is fighting Houthi rebels in Yemen.
