Bono is headed to the Hill.

The U2 front man and co-founder of the ONE campaign, an anti-poverty organization, is poised to testify Tuesday afternoon at a Senate Appropriations Subcommittee hearing on violent extremism and the role of foreign assistance.

A ONE spokesman tells ITK the politically active singer visited refugee camps in Kenya, Jordan and Turkey earlier this month. The sunglasses-sporting entertainer will “discuss the connection between immediate humanitarian response and long-term development efforts” at the Dirksen Senate Office Building hearing.

Bono, 55, is no stranger to Capitol Hill — the Irish-born entertainer has made several visits over the years to meet with lawmakers and testify before Congress.
