In an interview with ABC News, Sen. Ted Cruz, R-Texas, predicted his party would reclaim the Democratic-controlled Senate in November, but he declined to endorse current Senate Minority Leader Mitch McConnell, R-Ky., as the party leader should there be a transfer of power in the upper chamber of Congress.

"You know, I am very optimistic. I believe in November Republicans are going to retake the Senate and we're going to retire [Sen.] Harry Reid as majority leader," Cruz told ABC's Jeff Zeleny in New Hampshire Saturday night.

But when asked if he would endorse McConnell - currently embroiled in a tight race for his Kentucky Senate seat - as Senate majority leader, the Texas Republican said that is a decision that would be made "when the time is right."

"Well, that will be a decision for the conference to make, but I am confident we will have a new majority leader," he said.

"I will support the leader of the Republican Party," Cruz added when pressed by Zeleny.
