President Trump, first lady plan to travel to Texas Tuesday amid Hurricane Harvey

Harvey hit Texas as a Category 4 hurricane but has been downgraded.

"We are coordinating logistics with state and local officials, and once details are finalized, we will let you know," press secretary Sarah Sanders said in a statement Sunday afternoon.

She added, "We continue to keep all of those affected in our thoughts and prayers.”

First lady Melania Trump will accompany the president on his trip to Texas, her director of communications, Stephanie Grisham, confirmed today.

The president tweeted Sunday that he plans to visit Texas "as soon as that trip can be made without causing disruption."

Harvey, which hit Texas as a Category 4 hurricane but was downgraded to a tropical storm over the weekend, is forecast to still be in the region when Trump touches down in the state. Another 15 to 20 inches of rain are expected to fall over the Houston area before the storm moves northeast Wednesday or Thursday, according to the National Weather Service.

As a result of Harvey, Houston, the country's fourth-largest city, is dealing with record, life-threatening flooding.

Over the weekend, Trump monitored the storm from Camp David — first natural disaster of his presidency.

While he was a candidate for president, he paid a visit to Louisiana after deadly flooding hit Baton Rouge and parts of Lafayette in August last year. He, along with now–Vice President Mike Pence, inspected flood damage and helped unload a truck of supplies.
