Federal prosecutors were bearing down on him over his business dealings, some involving Trump, and Cohen was looking for a sign of reassurance from the President, a man he regarded more as family than as a boss.
Republican presidential nominee Donald Trump's personal attorney Michael Cohen stands behind Trump after a group of supporters plus vice-presidential nominee Mike Pence laid hands on Trump in prayer during a campaign stop at the New Spirit Revival Center church in Cleveland Heights, Ohio, US on September 21, 2016.
Giuliani also said that they've hired multiple experts to review and analyze the recordings of conversations between Cohen and Trump.
On Friday morning, the president reiterated that claim.
The comments about whether Cohen's release of the tape violated attorney-client privilege comes as sources tell ABC News that Cohen claims Trump knew in advance about a 2016 Trump Tower meeting between Trump campaign members and Russians who were expected to provide dirt on rival candidate Hillary Clinton.
"I did NOT know of the meeting with my son, Don jr", the President wrote on Twitter. "Every other participant in both those meetings say it's not true". The government has been totally ethical about this, ' Giuliani said.
"If you're asking me who do I believe, the president or Michael Cohen, with what Michael Cohen may say - for instance when Michael Cohen says, now, that the president knew about the Russian Federation meeting in advance - I would believe Don Jr. and the president, in light of learning that Michael was taping conversations, the way Michael was conducting himself behind the scenes and in front of all of us", Nunberg said. Trump has denied knowing in advance about the meeting.
A secret recording of Donald Trump discussing payments to a Playboy model has brought renewed attention to the question of whether and how he might have blocked politically damaging stories ahead of the 2016 presidential election.
Giuliani told Fox he has hired technicians to determine if someone tampered with the tape, which cuts off abruptly.

Meet The Wife Of The Open Contender Francesco Molinari
I loved seeing him jump to 20th. "I'm certainly happy for him". "It's not a nice feeling when I don't see the Claret Jug ". The silence that befell Carnoustie as the field dissolved into the distance was uniquely fascinating.
Trump Jr. said he did not remember who he was calling.
Giuliani, who called Cohen "an honest, honorable lawyer" as recently as May, has made a sport out of bashing Cohen in recent days. She has alleged that she had a months-long affair with Trump in 2006.
A former Trump Organisation employee told CNN his being subpoenaed is the "ultimate nightmare scenario for Trump", because Mr Weisselberg knows "anything and everything" about the financial details of the organisation.
The meeting was arranged through emails between a publicist and Trump Jr.
"Prosecutors prefer to strike cooperation deals quietly and in private because they want to save the impact of any valuable testimony and information that a cooperating witness can offer until trial", he said. He's been lying for years.
Following the report on the Trump Tower meeting, Giuliani told CNN's Chris Cuomo on Thursday that Cohen has "been lying for years. he's lied all his life", and said he doesn't "see how he has any credibility".
The remarkable about-face followed a year-and-a-half during which Cohen had grown increasingly estranged from Trump since the real estate mogul moved into the White House, leaving Cohen behind in NY with the title - but little of the responsibility - of personal attorney to the President and progressively dwindling access.
On Sunday, Giuliani told CBS that talks since have been interrupted by other issues, including the Cohen matter and Mueller's prosecution of former Trump campaign manager Paul Manafort.
The parties have been "distracted by all kinds of things", Giuliani said. His trial is scheduled to begin this week.
