United States President Joe Biden on Wednesday signed an executive order making sexual harassment an offense under the military's judicial code, a reform sparked by the murder of soldier Vanessa Guillén in 2020.

Biden's executive order also strengthens the military justice's response to cases of domestic violence and implements changes to the "military justice code to criminalize the wrongful broadcast or distribution of intimate visual images," the White House said in a statement.

The decree sets in motion some of the measures approved in the I Am Vanessa Guillén Act, which was ratified at the end of last year in Congress within the annual defense budget.

Guillén was 20 years old when in April 2020, she disappeared from the Fort Hood military base in Texas after having reported sexual harassment. Two months later her remains were found about 20 miles from the base, where she was killed.
