>>> tonight vice president joe biden 's son, beau, is spending the night at the m.d. cancer center in houston. beau biden , the attorney general of delaware , went with his father for tests this morning after feeling weak and disoriented on a family vacation last week. he was seen at dinner last night with his father, but people close to the bidens told nbc news the family is taking this quite seriously. chief medical editor dr. nancy snyderman is here with more. nancy, we don't know exactly what's going on here, but he did suffer a stroke three years ago when he was 41 years old. typically with a stroke patient, experience more problems down the line.

>> well, typically one-quarter of those stroke patients have had symptoms before. and we do know that since his strike, beau biden has had several episodes in the past. and that makes this serious. we have established tonight, nbc news has confirmed that he has been admitted to m.d. anderson for further testing. and having already been seen at two major medical centers around the country and now at m.d. anderson , the procedure that he's going to have is most likely a biopsy. the concern is always when there's a seizure and ongoing neurologic problems, you have to find out what the problem is. so to have him overnight, to most likely have a biopsy and then keep him for observation to allow the doctors to get tissue, make a correct diagnosis and then have a formulated and very smart game plan. and i know, lester, a lot of people have been asking, well, is this any correlation with what his dad went through 25 years ago with his aneurysm? and the answer is no.

>> hopefully we'll get some answers
