Donald Trump is pledging $1m (£774,000) in personal funds to Harvey storm relief efforts, the White House says.

Announcing the donation to reporters, White House press secretary Sarah Huckabee Sanders said Mr Trump was open to suggestions on which organisation to give the money to.

She said: "He's asked for me to check with the folks in this room, since you are very good at research and have been doing a lot of reporting into the groups and organisations that are best and most effective."

From the air: Flooded Houston

Harvey's floodwaters have heavily damaged tens of thousands of homes across Texas and the storm is now threatening the region near the Louisiana state line.

At least 31 people have been killed, including a family of six whose van was swept off a Houston bridge by violent flood waters.

On Tuesday, President Trump visited affected areas in Corpus Christi, Texas, telling rescue workers the flooding was of "epic proportion".

'Texas can handle anything'

He later tweeted: "After witnessing first hand the horror & devastation caused by Hurricane Harvey, my heart goes out even more so to the great people of Texas!"

Vice president Mike Pence also visited victims in Rockport, Texas, pledging the Trump administration's support until the state "rebuilds stronger and better than before".

Ms Huckabee Sanders said the President and first lady would return to Texas and Louisiana on Saturday, and will most likely visit Houston.

The city has been left devastated by Harvey, which has caused billions of dollars of damage and forced more than 32,000 into temporary shelters.

Texas governor Greg Abbott warned "the worst is not over yet" for the state, with flooding expected to persist for more than a week in some areas.

From Louisiana, Harvey is forecast to move inland and cause flooding in Kentucky and Tennessee.

The National Weather Service said some areas of Tennessee could get more than 25cm of rainfall, while high winds could also produce tornadoes.

Officials fear that as floodwaters continue to recede in Texas, rescue workers will recover more bodies.

Experts also say that floodwater samples from Houston show E.coli levels that are 125 times higher than is considered safe for swimming.

Texas A&M University microbiologist Terry Gentry said even walking through the water could cause infections and other problems.
