Questions are being raised about where the money will be sourced, and which charitable funds will be benefiting from it
Initially, it was thought that the money would come from Trump's own sizable fortune or his charity The Trump Foundation.
And despite the press enquiring as to where the money will be going, we're still none the wiser.
White House Press Secretary Sarah Huckabee Sanders told reporters during a recent briefing:
He [Trump] actually asked that I check with the folks in this room since you are very good at research and have been doing a lot of reporting into the groups and organisations that are best and most effective in helping and providing aid, and he'd like some suggestions from the folks here and I'd be happy to take those.
What should have been a straight-forward donation has already turned into a 'will he, won't he?' situation, and a number of people are not happy.
Among them is Twitter user Shauna (@goldengateblond), who has her own doubts over Trump's pledge.
The tweet soon attracted a lot of attention, garnering over 500 retweets and over 2000 likes at the time of writing.
Nearly everyone was in full support of her criticism of the President, but one Trump supporter took exception and challenged her protest.
