Delaware Attorney General Beau Biden is reportedly awaiting test results from a Houston-area cancer center Wednesday, after a health scare left him feeling weak and disoriented. Biden has not made any statements about his condition, but his entire family — including his father, Vice President Joe Biden — is with him in Texas.

"Beau Biden is being evaluated to determine the cause of an episode of disorientation and weakness that he experienced while on vacation with his family," the White House said in a statement.

According to the Associated Press, Biden was evaluated at the University of Texas MD Cancer Center. The 44-year-old felt sick during an August 14 road trip to Indiana, which led to him being admitted to Northwestern Memorial Hospital in Chicago. Upon discharge, Biden traveled to Philadelphia to consult another doctor. Now, with this trip to Texas for further evaluation, Biden’s supporters, constituents and family are becoming increasingly concerned.

"A lot of people all across the country woke up with Beau Biden on their minds," said White House spokesman Josh Earnest. This is not the first time Biden has had a health scare. In 2010, he had a mild stroke. After that incident he spent a week in the hospital and took a month off to recuperate at home.

On Tuesday, Biden tweeted his gratitude for everyone’s well wishes, but did not divulge any information about his illness. "Touched by all your well wishes—thank you. Nice evening in Houston w/ Hallie; will share update when we have it," the tweet read.

Reports early Wednesday say that Biden is awaiting results from tests he took at the cancer center. This story is still developing.
