Giuliani said he believes that the incoming president is being advised, in particular, by Serhiy Leshchenko, an opposition parliament member who helped uncover the off-the-books payments made to Trump campaign chairman Paul Manafort.
"I'm not going to go because I think I'm walking into a group of people that are enemies of the president, in some cases, enemies of the United States, and in one case, an already convicted person who has been found to be involved in assisting the Democrats with the 2016 election", Giuliani said.
Earlier Friday, Giuliani had defended going to Ukraine to press for an investigation into Biden's call to remove a top Ukrainian official in 2016, when Biden was vice president.
The alleged Biden conflict of interest questions that Giuliani and the president have referenced involves the then-vice president's 2016 call for Ukraine to crack down on corruption, including removing a Ukrainian prosecutor, Viktor Shokin, seen as ineffective.
Giuliani had previously told CNN that a "well-regarded investigator" he's known for years put him in touch last November with current and former Ukrainian officials, who he says he's interviewed over Skype and in person.
The trip raised the specter of a lawyer for Mr. Trump pressing a foreign government to pursue investigations that his allies hope could help him win re-election.
Giuliani's trip was first reported by the New York Times.

"Certainly, it would be an appropriate thing to speak about".
Giuliani wrote to Democratic Sen. What's more, this is a plot that goes back months.
Giuliani had said earlier that he would to travel to Kiev in coming days to urge the government to investigate the origins of special counsel Robert Mueller's recently concluded probe into Russian interference in the 2016 US election, and the involvement of former Vice President Joe Biden's son in a gas company owned by a Ukrainian oligarch.
Giuliani later cancelled that trip after facing intense criticism for seeking help from a foreign power to hurt a domestic political candidate, according to Politico. "Unfortunately, this is precisely what is now happening - thanks to President Trump's personal lawyer, Rudy Giuliani". He had told the publication he planned to ask Ukraine's new president, Volodymyr Zelensky, to look into the origins of special counsel Robert Mueller's Russian Federation investigation, as well as former Vice President Joe Biden's son's past connections to the country.
Sunday on ABC's "This Week", House Intelligence Committee chairman Rep. Adam Schiff (D-CA) said Congress should make it illegal for political campaigns to seek help from foreign governments to influence elections. Somebody could say it's improper. "I just want this investigated", Giuliani said.
Asked elsewhere in the Politico interview if he was disturbed that North Korea had fired short-range missiles, Trump said: "They're short-range and I don't consider that a breach of trust at all".
