Democratic presidential candidate Kamala Harris flew unexpectedly to New York on Saturday to appear on the "Saturday Night Live" TV program just three days before her election showdown with Republican Donald Trump.

Harris' campaign declined to comment, but two sources said she would appear on the popular comedy show, which airs at 11:30 p.m. ET (0330 GMT).

A "Saturday Night Live" appearance would add a surprise jolt ahead of the presidential election on Tuesday.
