The death penalty phase has wrapped up its first day in the trial of a man convicted of killing three people at two Jewish sites in suburban Kansas City.

Frazier Glenn Miller Jr. called himself to the stand Tuesday.

To support his anti-Semitic beliefs, he showed news articles and played videos of himself and others marching with Confederate flags.

He also played videos of prominent figures, including Russian President Vladimer Putin and longtime Klu Klux Klan leader David Duke.

He briefly interrupted his testimony to question Alex Linder, a Kirksville, Missouri, man described by the Southern Poverty Law Center as a neo-Nazi and operator of a racist website.

The prosecution called just one witness, a police detective.

Defense testimony will resume Wednesday.
