This is Gov. Greg Abbott.

It is our duty as Texas conservatives to support a leader that we can trust to restore our values.

That is why I am supporting Ted Cruz for president.

Unlike far too many in Washington, the Ted Cruz we’ve seen in the Senate is the same Ted Cruz that we elected. And he’s the same Ted Cruz I served with when I was the attorney general and Ted was the solicitor general.

Conservative values are at his core.

He’s principled, he’s fearless and he has true conviction.

Ted is a constitutionalist, whose judgment I trust to appoint the right judges to the United States Supreme Court.

To my fellow Texas conservatives, I say this—we need to deliver. This is our time. Ted Cruz is our candidate. Now let’s do our part to take this country back.

Abbott is the most senior political leader to back Cruz. No other sitting governor has yet endorsed him. Cruz has been endorsed by 23 of his Congressional colleagues, but no Senators.

The Texas primary will be held next Tuesday. Cruz, Sen. Marco Rubio and Gov. John Kasich are all under pressure to win in their home state primaries, which account for about a fourth of the GOP delegates up for grabs in the next three weeks.
