Texas Sen. Ted Cruz on vacation in Mexico amid storm crisis: AP source

DALLAS -- Texas Sen. Ted Cruz travelled to Mexico on Wednesday for a family vacation as his home state struggled with a powerful winter storm that left many residents without power or safe drinking water.

The high-profile Republican lawmaker went for a long-planned trip to Cancun and was expected to return almost immediately, according to a source with direct knowledge of the situation who spoke on the condition of anonymity to share private conversations.

Spokespersons for Cruz's office did not immediately respond to request for comment Wednesday night or Thursday.

The revelation opens Cruz, a key ally of former President Donald Trump, to fierce bipartisan criticism in Texas and beyond as he contemplates the possibility of a second presidential run in 2024. The two-term senator's current term expires in early 2025.

Hundreds of thousands of people in Texas woke up Thursday to a fourth day without power, and a water crisis was unfolding after winter storms wreaked havoc on the state's power grid and utilities.

Texas officials ordered 7 million people -- one-quarter of the population of the nation's second-largest state -- to boil tap water before drinking the water, after days of record low temperatures that damaged infrastructure and froze pipes.

In Austin, some hospitals faced a loss in water pressure and in some cases, heat.

Cruz's office has declined to release any details about the family vacation, but his staff reached out to the Houston Police Department on Wednesday afternoon to say the senator would be arriving at the airport, according to department spokeswoman Jodi Silva. She said officers "monitored his movements" while Cruz was at the airport.

Silva could not say whether such requests are typical for Cruz's travel or whether his staff has made a similar request for his return flight.

Cruz has been demonized by the left even before he ran for president in 2016. In more recent years, he has positioned himself as a Trump loyalist with an eye toward a potential second White House bid.

The Texas senator, who once described Trump as a "pathological liar," championed the-then president's call to block the certification last month of Democrat Joe Biden's election victory. That stand led to calls for Cruz's resignation after a violent mob stormed the Capitol as Congress was affirming Biden's win.

"Ted Cruz had already proven to be an enemy to our democracy by inciting an insurrection. Now, he is proving to be an enemy to our state by abandoning us in our greatest time of need," Texas Democratic Party Chair Gilberto Hinojosa said Thursday. "For the 21st time, the Texas Democratic Party calls on Ted Cruz to resign or be expelled from office."

Cruz's office dismissed calls for his resignation earlier in the month.

"The left -- and some grifters on the right -- are consumed by partisan anger and rage," his office said in a written statement. "Sen. Cruz will continue to work for 29 million Texans in the Senate."
