U.S. President Donald Trump has pledged to donate 1 million dollars in personal funds to Hurricane Harvey relief efforts, the White House said late Thursday.

White House Press Secretary Sarah Huckabee Sanders made the announcement at a briefing, saying he's calling on reporters to help decide which specific organization he will give to.

Trump has been praising the government's response to the storm on Twitter.

However, the has also been criticized in the past for giving far less of his income to charitable causes than many other multi-billionaires.

Tropical Storm Harvey sent devastating floods pouring into Houston on Sunday. Rising water chased some people to rooftops or higher ground and overwhelmed rescuers.

Harvey's flood waters have heavily damaged tens of thousands of homes across Texas and killed at least 30 people. The storm is now threatening the region near the Texas-Louisiana state line.

Trump tweeted earlier Sunday that he would be traveling to Texas as soon as he could go "without causing disruption."
