On Thursday, Senator Rand Paul single-handedly stalled a bipartisan effort to fast-track an additional $40 billion to assist Ukraine and its regional allies in the fighting against Russia. But this was not the first time the Kentucky Republican has opposed aid to Ukraine, nor is he the only Republican to object twice.

In March, the Senate successfully passed a $1.5 trillion appropriations package—which included $13.6 billion in emergency funds for Ukraine—but the legislation did not have the support of 31 Republican senators and 57 GOP representatives.

While the latest round of relief was overwhelmingly passed by the House on Wednesday, the same 57 Republicans who voted no in March doubled down on their opposition by voting against a Ukraine aid package for the second time.
