Back Monday after a five-week break, many lawmakers stand as a major obstacle to President Barack Obama's promised strikes against Syria amid fears of U.S. involvement in an extended Mideast war and public fatigue after more than a decade of conflicts in Iraq and Afghanistan.
Obama insists the world must act. He blames Syrian President Bashar Assad for gassing his own people, killing 1,429 civilians, including 426 children. The Syrian government has denied responsibility for the Aug. 21 chemical weapons attack outside Damascus, and blames rebels.
On Wednesday, the 12th anniversary of the Sept. 11 terrorist attacks, the first showdown Senate vote is likely over a resolution authorizing the "limited and specified use" of U.S. armed forces against Syria for no more than 90 days and barring American ground troops from combat. A final vote in the 100-member chamber is expected at week's end.
"I think we're going to get 60 votes. It's a work in progress," Senate Majority Leader Harry Reid, D-Nev., said Friday.
Support for the president is stronger in the Senate than in the Republican-controlled House. There, Obama faces a difficult path to victory despite the backing of Speaker John Boehner, R-Ohio, Majority Leader Eric Cantor, R-Va., and Democratic leader Nancy Pelosi of California for military strikes.
The Syria vote poses a dilemma for Obama's Democratic allies in Congress. Many strongly opposed the war in Iraq but are reluctant to undercut a president from their own party. The crucial player is Pelosi, a proven vote-getter.
"A lot of members have constituents who have not been persuaded and I think a part of that inability to be persuaded is that they're thinking about Iraq," Rep. Elijah Cummings, D-Md., said Friday after one of many classified briefings for lawmakers. "That's what I'm hearing in my district even from people who are extremely supportive of the president."
Senior administration officials will speak to lawmakers in advance of the president's speech to the nation Tuesday night.
A House vote is likely the week of Sept. 16.
Even before Syria, Congress faced a busy and difficult fall packed with battles.
Obama and his allies in the Democratic-run Senate face fights from House Republicans over bills to fund government agencies and raise the ceiling on federal borrowing to avert a market-rattling government default. Then there are efforts by conservatives to cut off money for Obama's health care law, with open enrollment for health insurance exchanges beginning Oct. 1.
After Syria, Congress's most immediate task is passing a temporary spending bill to prevent much of the government from shutting down on the Oct. 1 start of the new budget year.
The stopgap measure would buy time to work out funding government programs over the next 12 months, but even its passage is in doubt.
Republicans are divided over whether to use the measure as a last-ditch assault on Obama's expansion of federally subsidized medical care and new requirement that millions of people without health insurance either buy it or pay penalties to the Internal Revenue Service.
GOP leaders eager to avoid an impasse and government shutdown prefer a straightforward temporary spending bill that would keep agencies running at current budget levels reflecting the imposition of the automatic, across-the-board spending cuts in place for the past six months. But to pass it, they probably will need votes from Democrats unhappy that higher taxes aren't also on the table.
Congressional Democrats and the White House are eager to reverse the cuts, and many defense hawk Republicans would like to as well. But there have been no fruitful negotiations between the White House and House GOP leaders.
Negotiations between White House officials and a small group of Senate Republicans collapsed last month over familiar disagreements over tax increases and cuts to popular federal benefit programs.
Without a deal, those automatic spending cuts could become entrenched through all of next year and possibly into the next several years.

A 2011 agreement called for a total budget of $1.058 trillion next year to operate federal agencies. The automatic spending cuts triggered by failing to follow up with further deficit cuts by curbing benefit increases, raising taxes or both would pare that figure by $91 billion, to $967 billion for the 2014 budget year.
A comparable spending figure for the soon-to-be-completed 2013 budget year is about $988 billion, with the approximately $20 billion in additional defense cuts.
House Armed Services Committee Chairman Howard "Buck" McKeon, R-Calif., says many Republicans on his committee want to reverse the defense cuts as a condition for voting for the resolution authorizing military strikes on Syria.
Avoiding a shutdown is just one step.
The administration says the government's ability to fully pay all its bills, including interest payments to bondholders and Social Security benefits, will run out some time in October unless Congress raises the $16.7 trillion cap on its borrowing authority.
That legislation could be even more vexing because Boehner and tea party Republicans see it as leverage to force further spending cuts or other GOP priorities into law.
Obama agreed in 2011 to Boehner's demand that spending cuts equal the size of the debt limit increase, but the president says he won't do it again. Republican leaders say such a "clean" debt limit increase Obama wants is a nonstarter.
An immigration overhaul could get lost in the shuffle.
The Senate in June passed a broad bill that would allow millions of immigrants now in the country illegally to stay, work and eventually acquire citizenship. House Republicans reject what they call a special path to citizenship in the Senate bill and favor a piecemeal approach that begins with better securing U.S. borders before excusing most people who entered the country illegally or overstayed their visas from being deported.
Revelations this summer about the National Security Agency's spying prompted demands from some in Congress to rein in the programs; a series of hearings is scheduled. Leaders of the House and Senate intelligence committees face pressure from lawmakers to make changes to NSA surveillance in the longstanding authorization bills.
Lawmakers also are pushing for major changes in how the military handles cases of sexual assault in their ranks. A significant number of lawmakers want to remove commanders from the process of deciding whether serious crimes, including sexual misconduct cases, go to trial.
The Pentagon and some senior lawmakers reject that idea. A showdown is expected later this year when the Senate debates a defense policy bill.
Congress also will have to finish a farm bill before the end of the year if lawmakers want to avert the threat of milk prices doubling for consumers. Most of current farm law expires at the end of September, but its effects won't be felt until the end of the year when dairy supports expire. Without the supports, milk prices are expected to rise.
