Hurd is the third Republican from Texas to announce his retirement in the last week, as Democrats in the Lone Star State believe they have a chance to pick up a number of GOP seats in 2020.
“Texas is the biggest battleground state," said the Texas Democratic Party chief Manny Garcia. "Republicans know it, and Texas Democrats damn sure know it."
Hurd is currently the only Republican in Congress whose district runs along the southern border with Mexico.
There have been rumblings in recent weeks on Capitol Hill that a number of Republicans might announce their retirements from the House during the current summer break, as lawmakers aren't due back in Washington until after Labor Day.
For some Congressional veterans, the reason for the departures is obvious - it's the gulf between lawmakers and President Trump.
“Members of Congress who are retiring because they don’t want to continue to associated with the party of Trump owe it to their constituents and to all Americans to speak up and speak out about what they’ve seen behind the scenes, and why they are packing it in,” said ex-Rep. Carlos Curbelo (R-FL).
“The Republicans with any vestige of underlying decency— few of whom spoke out in any way— are jumping ship before they are forced even further into a moral abyss,” said Congressional expert Norm Ornstein.
