chagos islands
The president said he was "inclined to do along" with it just a day after the Tories urged him to block the agreement.
John Kennedy suggested the PM must be on drugs to support the handover of the Chagos Islands to Mauritius.
The PM has made reportedly concessions to Mauritius which could see the UK paying Mauritius billions more to take over the territory.
Despite the warm words between the pair, there is still much that could potentially divide them over the next four years.
It comes after the Mauritius PM questioned the agreement this week.
Navin Ramgoolam said it “would not produce the benefits that the nation could expect.”
The prime minister failed to give the guarantee when asked last week.
The move has been hailed by Joe Biden - but criticised by Tory leadership contenders.
