"You know, I'm the vote counter for the Senate now as the majority whip, and I think it's frankly helpful, given my seniority and my position in leadership, to continue to serve," Cornyn said at the Texas Tribune festival.

He added that he would stay in the Senate "as long as Texans will have me" and that his seniority has benefits for the state, including a larger initial package of recovery aid for Hurricane Harvey.

Cornyn is the Senate's second-ranking Republican. He is term-limited as majority whip after 2018.

"I told him I’d support him in his reelection, and I think it’s important to do so to send the message that Texans, when it comes to something like the recovery after this natural disaster, that we are going to stand together and not be distracted," Cornyn said on Sunday.

Cornyn had previously declined to endorse Cruz.

Rep. Michael McCaul (R-Texas) has been floated as potential primary challenger to Cruz.

"I'm not going to get involved in any primary races particularly with my colleagues in the Senate," Cornyn told CNN last year, when asked about the potential matchup. "We'll see what happens, but we've got plenty to worry about between now and November 2016 before we start worrying about November 2018."
