Outgoing Sen. Barbara Boxer is slamming a push by House Majority Leader Kevin McCarthy (R-Calif.) to attach California drought language to a waterways bill, calling the provision a “poison pill.” Boxer, a California Democrat, said the inclusion of the drought language would jeopardize bipartisan efforts to finalize the Water Resources Development Act (WRDA), which McCarthy said would be posted on Monday.

The underlying legislation authorizes dozens of water-related infrastructure projects around the country and is expected to include emergency funding for the lead-contaminated community of Flint, Mich.
