(CNN) The Trump administration is working behind the scenes to abandon a commitment of millions of dollars in funding for the World Health Organization, despite President Donald Trump's announcement on Tuesday that his administration was pausing funding while reviewing the group's handling of the coronavirus pandemic, CNN has learned.

The move to completely slash the current allocated funding and prevent additional funds from being sent to the organization will set up a fight with Congress as the country is already struggling to handle the coronavirus pandemic.

The consideration to cut funding from the WHO comes in the middle of the worst global pandemic in decades and as Trump continues to defend his handling of the outbreak in the United States and seeks to deflect blame.

The administration's review is focused on determining where to reprogram the WHO funds, a senior administration official told CNN. The official added that all of the funding that hasn't been sent to the WHO already is going to be held, with the intention of reprogramming it. That official said there was not a specific timeline for the review, but noted that statutorily these kind of reviews are typically 60 days.

At least half of the money the US promised it would give to the WHO in 2020 has not yet gone out the door, said a source familiar with the spending. The administration is looking for new ways to spend that money, which will leave the WHO without tens of millions of dollars it was expecting. The US is the largest donor to the international organization.
