US President Donald Trump denies any wrongdoing in the case of a former Playboy model, who allegedly had an affair with him, lashing out at his lawyer for taping him while talking about hushing her.

“Inconceivable that the government would break into a lawyer's office (early in the morning) – almost unheard of,” Trump wrote on Twitter Saturday morning. “Even more inconceivable that a lawyer would tape a client – totally unheard of & perhaps illegal. The good news is that your favorite President did nothing wrong!”

The tape is among troves of documents and materials seized by the FBI after raiding the New York home of Trump’s former personal lawyer Michael Cohen in April.

The recording about the former Playboy model, Karen McDougal, occurred prior to the 2016 election, which yielded President Trump.

Trump and Cohen are heard in the recording while they are discussing paying hush money to McDougal, who says she had an affair with Trump in 2006, shortly after the birth of his youngest son.

Trump has been under pressure over growing allegations of sexual misconduct.

Cohen's attorney, Lanny Davis, told CNN in a statement that the recording would not hurt his client.

“Obviously, there is an ongoing investigation and we are sensitive to that,” Davis said. “But, suffice it so say, that when the recording that has been widely reported is heard, it will not hurt Mr. Cohen. And any attempt to spin cannot change what is on the tape.”

Trump's personal lawyer Rudy Giuliani has claimed that the recording, which occurred at Trump Tower in September 2016, is not detrimental to Trump, making Davis wonder why the president and his lawyer are so “angry.”
