President Trump and members of his Cabinet bowed their heads in prayer as they met at Camp David in Maryland before the president offered words of support for those impacted and still threatened by Hurricanes Harvey and Irma.

"All of American continues ... to pray for the families affected by Hurricane Harvey, Hurricane Irma which looks like it's really going to be a bad one. But we're prepared. We're as prepared as you can be for such an event," Trump said in a video posted on his @realDonaldTrump Twitter account. "All of America grieves for those who have already lost their lives."

Trump also said of Irma, which is heading to Florida as a "major" hurricane, that "we've never seen anything like this."

High atop the agenda was the government's preparation for the impact of Hurricane Irma. Trump and the Cabinet received updates throughout the day, according to a pool report, and received a briefing from acting Department of Homeland Security secretary Elaine Duke. Hurricane Harvey slammed parts of Texas and Louisiana last month.

A White House official said that Trump and first lady Melania Trump were keeping people affected by Hurricanes Harvey and Irma in their prayers, and encouraged everyone to listen to local authorities. In the video he shared, Trump issued this message to those in the path of the storm: "Property is replaceable, but lives are not."

Trump also recognized Vice President Mike Pence for leading a "wonderful" opening prayer, a photo of which was shared by the White House.

A readout from the White House issued Saturday evening said Trump, Pence and the Cabinet were briefed on Hurricanes Irma and Jose.

"President Trump directed Federal agencies to continue supporting State and local efforts to save lives, promote shelter efforts, and expedite requested assistance to affected areas," the readout said. "The President also commended his team for remaining focused on Hurricane Harvey recovery efforts in Texas and Louisiana. He urged people in the storm's path to follow the directions of their State and local officials and emergency responders. The President, Vice President, and their Cabinet extend their thoughts and prayers to those affected."

It was an otherwise quiet start to the weekend for Trump, who hadn't made any press statements Saturday and only tweeted a few times to share information about services available in Florida ahead of the storm.
