Congress and the White House are headed for a week filled with sharp, partisan disagreements that will include more FBI testimony on Hillary Clinton's emails, a vote to override President Obama's veto, and possibly even a partial government shutdown if the two sides can't find a spending agreement.

Lawmakers have been itching to get back to the campaign trail, but first have to find a spending agreement to fund the federal government past the end of the fiscal year on Sept. 30. So far, however, there's been no easy way forward, which is once again raising the prospect of a shutdown.

Republicans in the Senate have offered up a bill funding the government through Dec. 9 that would also provide $1.1 billion to fight the Zika virus. And while Senate Majority Leader Mitch McConnell, R-Ky., has scheduled a Tuesday vote to advance that bill, Democrats are likely to block it.

Democrats say they won't vote for the bill unless it contains a provision providing more than $200 million for Flint, Mich., where lead has contaminated the water supply.

Democrats have support from the White House here. On Friday, White House press secretary Josh Earnest said President Obama believes Congress has "more work to do" on the legislation and it is "not at all clear" he will sign it.

Republicans are hoping to mollify Obama and Democrats by including the money in a separate bill that authorizes federal water projects. The House will take up the water projects bill next week, and according to a source familiar with the legislation, it is "likely" to include money for Flint. A Senate-passed version already includes the Flint aid.

In the middle of that fight, Republicans in the House and Senate are expected to push for a vote to override Obama's decision to veto legislation that would let families of the victims of the Sept. 11, 2001 terrorist attacks to sue the Saudi Arabian government.

Obama opposes the bill because he believes it threatens U.S. immunity from lawsuits and would undermine relations with Saudi Arabia, a critical U.S. ally. But the bill is so popular, both chambers are expected to find the two-thirds support needed to override Obama's veto, and hand Obama an embarrassing defeat.

The two parties will also continue their fight over Hillary Clinton's emails, an issue Republicans have refused to let go after the FBI said it would not seek charges against Clinton or her team related to their handling of sensitive and classified information on Clinton's personal email server.

Republicans on the House Judiciary Committee will grill FBI Director James Comey again on his decision. The hearing will also give lawmakers a chance for both parties to ask about the "challenges" the FBI has faced trying to track terrorism threats.
