A Democratic National Committee member is proposing a symbolic resolution for consideration at a DNC meeting next month to reject the American Israel Public Affairs Committee’s massive spending on Congressional races.

The measure, sponsored by a young DNC member from Florida, could put party leaders on the spot about the pro-Israel lobbying group’s outsized role in Democratic primaries.

A lobbying behemoth that for decades courted lawmakers on both sides of the aisle, AIPAC has become an increasingly toxic brand in the Democratic Party.

In recent years, Israeli leaders and their backers in Washington have become more closely aligned with Republican politicians. At the same time, however, AIPAC’s super PAC has focused tens of millions in spending on Democratic primary races.
