(CNBC) — President Donald Trump’s attorney, Rudolph Giuliani, insisted that ‘truth is not truth’ when it comes to the investigation probing Russia’s role in influencing the 2016 elections, as he voiced anew his concern that the president could be lured into a perjury charge by the special counsel.

In an appearance on NBC’s “Meet the Press” on Sunday, Giuliani rejected the idea that his team was slow-walking a request by Robert Mueller’s team to interview Trump. The former New York City major insisted he would not be “rushed” into making his client available for something that could become a chargeable offense under the law.

“So what I have to tell you is, look, I’m not going to be rushed into having him testify so he gets trapped into perjury,” Giuliani told the program. He dismissed the idea of Trump having any foreknowledge about Russia’s efforts, or potentially obstructing the subsequent inquiry.
