(Portland, OR) -- Mayor Ted Wheeler is denouncing acts of destruction and violence after Portland protests over the Kyle Rittenhouse not-guilty verdict turned into a riot Friday night. Wheeler took to Twitter on Saturday saying that while he supports peaceful protests, he "strongly condemn(s) any acts of criminal destruction and violence." The Multnomah County Sheriff's Office said they declared the demonstrations a riot when they saw people damaging a gate to the detention center. Police say people near the Justice Center on Southwest 2nd Avenue and Madison Street broke windows and damaged doors at city buildings. The demonstrations were in protest of the jury's decision to acquit Rittenhouse of all charges against him in the shooting that left two dead and another wounded during a civil uprising in Kenosha, Wisconsin last year.
