Ted Cruz took aim on his Democratic challenger in November, Rep. Beto O'Rourke.
O'Rourke is expected to address supporters across the state via Facebook Live sometime Tuesday night.
Audio will be available later today.
CNN has rated the race as Likely Republican.

"It's clear Texas Democrats are fired up, exceeding expectations, and charging forward to November", Texas Democratic Party chairman Gilberto Hinojosa said.
"My focus is on representing 28 million Texans", Cruz, who is only 47 and has time for another presidential bid, said on a recent conference call with reporters.
Harold Cook, a longtime Democratic consultant, disagreed, saying O'Rourke's performance is a reflection of the Democrat wisely not spending mega-bucks on raising his name ID ahead of a primary that he knew he'd win. No Democrat has won a race for either since.
"Virtually every time someone has run against a Latino surname for U.S. Senate or for governor in the past two decades, that person [with the Latino surname] has received about 20 percent of the vote", said Manny Garcia, deputy executive director of the Texas Democratic Party. Democrats hope that Texas could finally be starting to turn into a purple - or even blue - state, a possibility speculated about since the 2016 election, as NBC News reported. In the first month and half of the year, he raised more money than Ted Cruz ($2.3 million to $800,000), and he seems poised to have the funds he needs to be competitive in the general election. Of the almost 50 women running for Congress in Texas, more than half won their primaries outright or advanced to runoffs. "It just stuck", he told CNN in a phone interview Tuesday. That is to say, incumbent junior Senator Ted Cruz easily coasted into his state's GOP nomination for his seat.
Wilson, the political novice among all these folks, described the results as reflecting a "women's wave" as much as the heralded "blue wave", adding, "I think that wave will continue, as long as women feel like our voices are not carrying the way that they should". "This is one way for Cruz to indirectly signal that he's not". "Last night's results, in my opinion, validated all of that".
