The Republican governors of Texas and Arizona have increased the number of National Guard troops they will deploy to the southern border to assist with security operations. The increases are part of President Trump’s recent plan to work with border-state governors to combat what he called a growing threat of unauthorized immigrants and drug trafficking from Central America.

By the numbers: Texas Gov. Greg Abbott said the state would boost the number of troops from 250 to at least 1,000, up from 250, per the AP. And Arizona Gov. Doug Ducey tweeted that 338 troops will be dispatched, up from 113.
