Speaking during a joint press conference with Sir Keir at Chequers, Mr Trump compared Britain's small boats crisis to the influx of migrants in his own country.
He said: “What I saw happening, with millions of people pouring into our country, I couldn’t stand to watch it, and we’ve done a great job.”
Speaking alongside Sir Keir, Mr Trump added: “The last three months we had zero – from millions of people a year ago, we had zero people enter our country illegally”.
In a wide-ranging press conference, the President added that Russian despot Vladimir Putin had "let him down" over Ukraine and the only thing he and Mr Starmer disagree about was Gaza.
Bizarrely he said he did not know former US Ambassador Peter Mandelson, who was sacked last week over his links to convicted paedophile Jeffrey Epstein.

Earlier, Mr Trump flew over by helicopter, having said goodbye to the King and Queen at Windsor Castle. His wife, Melania, stayed behind to tour the Royal Library with Camilla.
Last night, Mr Trump described the bond between the US and the UK as “priceless and eternal" after a day of pomp and pageantry for his unprecedented second state visit.
His speech said: “We’re joined by history and faith, by love and language and by transcendent ties of culture, tradition, ancestry and destiny.“
"We’re like two notes in one chord or two verses of the same poem, each beautiful on its own, but really meant to be played together."
Earlier in the day, Mr Trump enjoyed a carriage procession through the grounds of Windsor accompanied by a sovereign's escort of 80 mounted soldiers - similar to scenes from Trooping the Colour - and a 120-strong guard of honour, the largest staged for a state visit in living memory.
