Sen. Dianne Feinstein had to be corrected and told to vote during a Senate Appropriations Committee hearing.

Her office says that all of her scans were clear and she returned home.

When she returned to the Senate in May, her office at the time said she was still experiencing some side effects, including vision and balance issues that require her to use a wheelchair at times.

But just a week later, audio was made public from her exchange with a Los Angeles Times reporter where Feinstein appeared to not know she had been away from Washington for months.

Her office later said she was preoccupied and didn't realize debate had just ended.
