The cameras also caught the US leader appearing to struggle to keep his eyes open.
He seemed on the verge of nodding off as he sat at the front of the packed cathedral.
In his eulogy to the Republican Senator,Trump also recalled leaking Graham’s phone number.
The pair became allies but were locked in a bitter feud in the summer of 2015,when Graham called Trump a ‘jacka**’.
Trump then read out Graham’s phone number on stage for the world’s media.
Reflecting on the moment last night,Trump said: ‘So naturally,I did something that I shouldn’t have done. I shared his personal cell phone number with the millions of people that happened to be watching that particular day as I made a speech.
‘And I remember the number: 202-228-0292,if anybody wants to give it a shot. His phone exploded.
‘But it was Lindsey who had the last laugh,because while I blew up his phone for one day,we became great friends,and Lindsey did not stop calling me for the next 10 years. It was not easy.’
