Republican presidential candidate Mitt Romney says President Barack Obama's latest move to improve ties with Israel doesn't go far enough.

Obama is set to sign legislation Friday to expand military and civilian cooperation with Israel. The bill reiterates U.S. support for a negotiated two-state solution in the Israeli-Palestinian conflict.

The Republican's campaign says Romney is happy steps are being taken to enhance security cooperation with Israel. But that the bill "does nothing" to address whether Obama recognizes Jerusalem as the capital of Israel.

Obama's move comes one day before Romney visits Israel. Romney was scheduled to arrive in Jerusalem on Saturday as part of an overseas trip that includes stops in Britain and Poland.
