WATCH: Trump gives family of fallen officer an awkward compliment at police memorial service

President Donald Trump on Tuesday paid tribute to a fallen police officer with a strange remark about the dead cop's genetics.

During an address at a memorial for fallen police officers on Capitol Hill, Trump turned to one person in attendance behind him and told them that "your mom's legacy will never die," before then stating that the person's mother had "good genes" and "the best genes I've ever seen."

Talking about people's genetic makeup is something of an obsession for Trump.

In the past, he has openly boasted about his family's genes, and has even gotten his own personal physician to issue glowing reports about his allegedly superior DNA.
