Sen. Rand Paul, R-Ky., reacted Sunday to a New York Times report that his colleague Sen. Ted Cruz, R-Texas, had privately dismissed him as a presidential candidate.

According to the report, Cruz told donors in New York that Paul would have difficulties running for president because he could never detach himself from the libertarian-oriented political career of his Republican father, Rep. Ron Paul of Texas.

Paul was asked about the Times report during an interview on ABC's "This Week" with George Stephanopoulos.

"Ted and I are friends," Paul replied. "And he's a limited government conservative. We don't always agree on everything, but we agree on a lot of things. So I won't be coming on television to try to disparage him, whether we're ever rivals or not."

Paul added that he would continue to fight for the right to privacy and to criticize the National Security Agency because it was an issue that mattered to young Americans.

"Young people don't care so much about taxes and regulation, but they've all got a cell phone and they're all on the Internet and they do care about their privacy," he said.

Paul wouldn't say whether or not he would run for president in 2016.

"I think we're a long way away from that. I haven't even convinced my wife yet whether I should do this," he said. "So we're a ways away from making a decision."
