House Republican leaders are hoping to pass legislation next week that would require the federal government to conduct a comprehensive analysis of threats coming across the southwestern U.S. border.

The Southwest Border Security Threat Assessment act, from freshman Rep. Martha McSally, R-Ariz., is a response to growing fears that Islamic State terrorists are looking to enter the U.S. from Mexico, and plot terrorist acts in any U.S. city they can reach. McSally said her bill would help Congress get a better handle on how real these threats are, and provide a needed update for border agents.
