President Donald Trump on Wednesday said the U.S., which has the most cases of coronavirus of any nation in the world, has possibly passed its peak for infection numbers.

"The battle continues but the data suggests that nationwide we've passed the peak on new cases," Trump said from the White House Rose Garden. "Hopefully that will continue."

He pointed to positive trends in the the New York metro area, Denver, Washington, D.C., Baltimore, Philadelphia, St. Louis, Houston and New Orleans.

"These encouraging developments have put us in a very strong position to finalize guidelines for the states on reopening the country," Trump said, adding that the guidance will be announced on Thursday.

He said some states might be able to open up before May 1, adding that they're "chomping at the bit."

Other areas, however, aren't doing as well.

Deborah Birx, a member of the White House coronavirus task force, said Providence, Rhode Island is a spot of concern due to its location between two hotspots in New York and Boston.

"Rhode Island and Providence are in a unique situation," Birx said. "First, they had increasing cases from the New York City area, and now they have new increase in cases from the Boston area."

Birx said that governors and mayors will have to make their own decisions about reopening after the generalized new guidelines are released.

She said that nine states have fewer than 1,000 cases of the virus, with less than 30 new cases being reported each day. Nationally, U.S. health officials report nearly 635,000 cases of the virus and close to 28,000 deaths.

Trump added that he is considering using constitutional authority to adjourn both chambers of Congress so that he can appoint his nominees for key positions without waiting for confirmation from the Senate.

"I have a very strong power. I'd rather not use that power, but we have way over a hundred people that we very badly need in this administration that should've been approved a long time ago," Trump said.
