WASHINGTON, D.C. - Youngstown mayor Tito Brown is among 50 mayors from around the country in Washington D.C. this week as a part of the United States Conference of Mayors' efforts to find solutions to homelessness. 

The gathering comes after the group conducted a survey highlighting their top concerns and homelessness was cited as the top concern from most of its members, with 48 percent listing it at the top, ahead of economic development, public safety and transportation/infrastructure. 

The issue causing the least concern on the survey was immigration, with only 1.9 percent citing it as one of the biggest challenges facing cities today. 

During the two-day event, Brown and the other mayors met with members of Congress and the Biden administration to advocate for federal and local partnerships, expanded housing vouchers and finding ways to lower housing costs. 

Brown is the only mayor from the Mahoning Valley attending the conference. His office did not announce his attendance publicly in advance of the trip. 21 News is working to get more details on what Brown's focus was for the trip or what solutions he hopes to implement in Youngstown. When reached by phone on an unrelated matter, Brown was still in D.C. and said he was unavailable to speak at the moment.
