"Tomorrow, the president will deliver remarks announcing the (Iran) strategy to the country, White House Press Secretary Sarah Sanders told reporters at her daily news conference.
She however, gave no indication of what the Iran strategy would be.
However, media reports said that the president might pull out of the Iranian nuclear agreement.
Democratic leader Nancy Pelosi cautioned against leaving the Iranian nuclear agreement, which was one of the top foreign policy achievement of the former president Barack Obama.
"Experts agree that the Joint Comprehensive Plan of Action remains the best way to prevent Iran from acquiring nuclear weapons. Failing to certify the Iran Nuclear Agreement would be a spectacularly dangerous and reckless decision that puts Americas national security at risk and the catastrophic threat of a nuclear-armed Iran back on the table," Pelosi said.
The agreement has set up the toughest international monitoring regime ever enacted.
The JCPOA has also allowed the international community to make progress in holding Iran accountable for its continued support for terrorism and its many human rights violations, she said.
