Formerly of the Texas Public Policy Foundation, Treviño will be the newest commentator for the Guardian's growing US politics team through his column On Politics & Persuasion which launches on Monday 20 August.
"We are pleased to have Josh join the Guardian," said Janine Gibson, editor-in-chief of the Guardian US. "He brings an important perspective our readers look for on issues concerning US politics," added Gibson.
Treviño's background spans from speechwriting for the Bush administration to conceiving and co-founding RedState. Treviño is also a writer-at-large for the magazine Texas Monthly.
Treviño said: "Joining the Guardian as a US politics commentator is a tremendous honor, and I genuinely look forward to engaging with the savvy, informed, and active global community of Guardian readers. My background in communications and activism has given me insight into what works and what doesn't in the digital age. The Guardian works, largely because of its forward-looking strategy of comprehensive reader engagement that is rooted in an ethic of intellectual openness. Joining the Guardian is a privilege."
Last month the Guardian announced that Glenn Greenwald would be joining its US commentary team from Salon. Treviño and Greenwald bring their distinctive voices to a strong team of political and cultural commentators that includes Ana Marie Cox, Michael Wolff and Naomi Wolf.
