Last week, the presenter was discussing the US President's comments that he had been taking unproven and controversial drug hydroxychloroquine to prevent coronavirus.
After watching a clip of Trump speaking about taking the medication, Phil said: "He's still there, sadly."
Viewers slammed Phil's comments on Twitter.
What did they say?
One person said: "Nice of @Schofe to be wishing death upon @realDonaldTrump just now."
Another ranted: "@thismorning think @Schofe's comment regarding @realDonaldTrump is disgusting.
"He should be made to make an apology or he shouldn’t be on the TV anymore as these comments are not acceptable."
Following the criticism, Phil cleared things up on Twitter and insisted his comment was taken the wrong way.
The majority are about Philips’s comments about Donald Trump.
He wrote: "Still in OFFICE!! Not still alive FFS!!!"
However, despite the confusion, Ofcom still received complaints from viewers over Phil's remark.
A spokesperson for the TV watchdog told The Sun: "Of the 51 complaints about This Morning we can confirm that the majority are about Philips’s comments about Donald Trump."
Ent Daily has contacted reps for Phil and This Morning for comment.
Before Phil made his comment on This Morning, Dr Hilary Jones warned people against taking hydroxychloroquine.
He explained on Good Morning Britain: "It’s very dangerous to advise, when you’re not qualified, a drug which is quite toxic.
"If you look at the list of side effects, they’re huge; bone marrow suppression, deafness, heart irregularity, liver damage.
"And he’s saying to people go and take it – he’s like a drug pusher!"
