US representative files resolution decrying rightwing calls for invasion of Mexico

Joaquin Castro urged fellow House members to reject Republican calls for US military action to stem flow of fentanyl from Mexico

A progressive US congressman from Texas has asked his legislative colleagues to join him in condemning some American conservatives' calls to invade Mexico - ostensibly to do battle with drug cartels there.

Joaquin Castro says he intends to file a resolution in the US House as soon as Friday reaffirming the federal government's commitment to respecting the sovereignty of Mexico and condemning calls for military action without Mexico's consent and congressional authorization".
