7:30 AM PT -- Senator Dianne Feinstein's office released this statement ... "Senator Feinstein briefly went to the hospital yesterday afternoon as a precaution after a minor fall in her home. All of her scans were clear and she returned home."
Senator Dianne Feinstein was at the hospital, TMZ has learned, after tripping and falling Tuesday in her home city of San Francisco.
We do not know how serious her injuries are ... only that she was taken to a nearby hospital. We're told she returned home Tuesday night.
The 90-year-old Senator has struggled with health issues over the last year. She was absent from the Senate for nearly 3 months earlier this year dealing with shingles, Ramsay Hunt syndrome and encephalitis.
She's also appeared confused ... telling a reporter upon her return she wasn't absent at all. She's also appeared confused at recent Senate hearings.
There have been quiet talks among Democrats and louder talks among Republicans for her to step down.
We reached out to the Senator's officer for comment ... so far, no word back.
