WASHINGTON (AP) — Democrats are pushing to reopen talks on must-do legislation to prevent the government from shutting down this weekend, fight the Zika virus and help flood-ravaged Louisiana rebuild.

The aim is to see if Republicans will relent and add money to help Flint, Michigan, with its water crisis — and get Capitol Hill off a collision course that could lead to a government shutdown this weekend.

Democrats are expected to block the stopgap funding bill Tuesday afternoon if GOP negotiators don’t offer funding to help Flint and other communities with lead-poisoned water replace pipes and take other steps.

An alternative option would be for Majority Leader Mitch McConnell to strip $500 million in flood aid for Louisiana and other states from the bill. Democrats don’t want that, either.
