Joe Biden says ‘I have seven grandkids’ after acknowledging four-year-old Navy

President had previously failed to publicly mention Navy, daughter from Hunter Biden's relationship with Lunden Roberts

For the first time in an interview, Joe Biden acknowledged he has seven grandchildren, including Hunter Biden's four-year-old daughter Navy.

I have seven grandkids," the president said, five of 'em old enough to talk on the phone, you know, every day I either text or call them."
