Per Recode, Trump told reporters on Air Force One that he "didn't make that decision-it was made by a man who's a very respected person, a very, very respected person".
In the run-up to last year's election he vowed that as president his Justice Department would block AT&T's purchase of Time Warner.
Stephenson said several times on Thursday that a combined AT&T and Time Warner will create a data and advertising company whose competitors will be the newest and most disruptive entrants into the media sector, Amazon.com Inc, Facebook Inc, Netflix Inc and Alphabet Inc's Google, not other wireless phone companies.
"I do feel you should have as many news outlets as you can - especially since so many are fake", Trump continued, according to a pool report.
Delrahim has said he prefers "structural" changes to a deal, like selling off assets, rather than having the government monitor a company's promises to abide by certain conditions, as was done with Comcast. The move is likely to draw criticism and could be seen as political payback, since US President Donald Trump has repeatedly criticized CNN for its coverage of him, calling it "fake news".More news: Veterans Day events scheduled in the area

Trump on Saturday also maintained he had not been involved. The Wall Street Journal has revealed that Kushner was particularly very annoyed with the cable news agency's "fact-checking" during the presidential campaign.
Delrahim said he had not had any contact with the White House or the attorney general on the matter, speaking at an event at the USC Gould School of Law in Los Angeles later in the day.
"We have been working very diligently on a litigation strategy and a litigation plan", he said, adding: "We would obviously ask for an expedited hearing".
AT&T CEO Randall Stephenson has denied that his company would ever sell CNN, while Vanity Fair reported some in media are speculating Murdoch has been quietly urging Trump to tank the merger in revenge for Time Warner declining an $80 billion buyout offer in 2014.
