Nov. 24 (UPI) -- The White House delayed rolling out a new plan Monday that was expected to curb rising healthcare costs, as major Affordable Care Act subsidies expire for millions at the end of the year.

President Donald Trump had been scheduled to unveil his plan Monday, but the announcement was postponed without a reason, a White House official told CNN.

"Until President Trump makes an announcement himself, any reporting about the administration's healthcare positions is mere speculation," White House spokesman Kush Desai said.

Earlier Monday, MSNOW also reported the administration would introduce a new proposal aimed at curbing premium hikes, that could more than double with the expiration of ACA subsidies. By the end of the day, there had been no announcement on the plan, even though it was never officially on the schedule.
