U.S. Sen. Sheldon Whitehouse of Rhode Island says he has been weighing whether to show his face at the U.N. climate talks that kick off Sunday in Scotland.

He wants to make the trip, "unless it's too humiliating to go (because) we've completely disgraced ourselves in Congress."

Congressional Democrats' stalled push to enact key parts of U.S. President Joe Biden's climate agenda has Democratic lawmakers concerned that they are undermining Biden's message in Glasgow even before he arrives.
