Rep. Mike Turner (R-OH) on Sunday stressed the urgent need for continued support to Ukraine, saying he is “very concerned” about House Republican leadership’s surprise bid to pass a stand-alone Israel aid bill.

During an appearance on CBS News’s Face the Nation, Turner was joined by Rep. Jim Himes (D-CT) as the two seek a bipartisan approach to foreign aid issues ahead of Senate negotiators releasing details on a bill that is expected to include aid for the Jewish state as well as Ukraine, Taiwan, and border security.
