WASHINGTON, Oct. 7 (Xinhua) -- U.S. President Donald Trump returned to the Oval Office at the White House on Wednesday while still recuperating from COVID-19.

Trump was briefed on economic stimulus talks and Hurricane Delta, a potentially devastating storm heading toward the Gulf Coast, according to White House spokesman Brian Morgenstern.

The president later tweeted himself that he had spoken to governors of Texas and Louisiana on the hurricane, which is expected to hit the southern coastal region later this week.

"Please heed the directions of your State and Local Officials," he wrote. "We are working with them very closely - please be prepared, be careful, and be safe!"
