Obama, Boehner remain at odds on verge of fiscal cliff NEW: Stocks drop on news of the latest impasse in fiscal cliff talks President Obama suggests Republicans are fixated on besting him personally Speaker Boehner says the House will pass his fallback tax plan Thursday Washington (CNN) -- After progress earlier this week in fiscal cliff negotiations, President Barack Obama and House Speaker John Boehner firmly butted heads Wednesday to set up a showdown in the final days left to reach an agreement. The incremental negotiations had focused on a roughly $2 trillion package of new revenue, spending cuts and entitlement reforms the two sides have shaped into a broad deficit reduction plan. Boehner added a new wrinkle on Tuesday by proposing his plan B -- a limited tax measure to extend Bush-era tax cuts on income of $1 million and below. He described it as a fallback option to prevent a sweeping tax hike while negotiations continue on the broader overall plan. In a candid assessment of the tough talks Wednesday, Obama told reporters that Republicans are focused too much on besting him personally rather than thinking about what's best for the country. "Take the deal," Obama said to Republicans, referring to the broader proposal under discussion, saying it would "reduce the deficit more than any other deficit reduction package" and would amount to a significant achievement. "They should be proud of it," Obama said. But they keep on finding ways to say 'no.' as opposed to finding ways to say 'yes.'  The comments at a White House news conference came less than two weeks before the nation faces automatic tax increases on everyone, as well as deep spending cuts due to the fiscal cliff at the end of the year. Economists warn that failure to reach agreement could bring another recession, and investors appear to be closely watching the negotiations. After gains this week on news of progress in the talks, stocks fell Wednesday due to the latest impasse in the talks. Boehner followed Obama's remarks with his own statement Wednesday, saying the president had yet to make a proposal offering his promised approach of balance between increased revenue and spending cuts. In his 52-second appearance before reporters, Boehner said the House will instead pass his fallback tax plan Thursday that limits tax hikes to income above $1 million. While a concession from his original opposition to any kind of increase in tax rates, the Boehner plan sets a significantly higher threshold for a rate hike than the $400,000 level sought by Obama. Once the House passes his plan, the president can either persuade Senate Democrats to accept it or "be responsible for the largest tax increase in American history," Boehner said before walking off without answering shouted questions. The Obama administration and congressional Democrats said Boehner changed course because he was unable to get Republican support for the larger deal being negotiated with Obama. At his news conference, Obama alluded to last Friday's Connecticut school shootings in calling on Republicans to put aside such political brinksmanship, saying that "if there's one thing we should have after this week, it should be perspective about what's important." "Right now, what the country needs is for us to compromise," he said, calling what he characterized as a GOP refusal to accept a reasonable compromise on the table as "puzzling." Asked why an agreement proved so difficult to attain after both sides made major concessions in the past week, Obama said it might be that "it is very hard for them to say 'yes' to me." "At some point they've got to take me out of it," Obama said of Republicans, adding they should instead focus on "doing something good for the country." Boehner responded by arguing that Obama's latest proposal was not evenly balanced, with more new revenue opposed by Republicans instead of the spending cuts and entitlement reforms they seek. With automatic tax hikes looming for all, Boehner said, his plan B proposal would "make permanent tax relief for nearly every American." Obama said Wednesday the Boehner proposal "defies logic" because it raises tax rates on some Americans, which Republicans said they didn't want, and lacks any spending cuts, which Republicans say they do want. He also criticized the Boehner measure as a benefit for wealthy Americans, who also would have lower tax rates extended on their income up to $1 million. The White House and congressional Democrats say the Boehner plan B has no chance of passing Congress, and Obama added that bringing it up now wastes time as the deadline for an agreement looms closer. This week, Republican Rep. Steve Womack of Arkansas called Boehner's move a negotiating tactic, and GOP leaders sought to corral support for the plan B option. They planned to vote Thursday on Boehner's proposal, as well as Obama's long-standing demand to return to higher tax rates of the 1990s on income above $250,000 for families. Conservative allies publicly supported Boehner's plan Wednesday. Anti-tax crusader Grover Norquist provided political cover for Republicans who signed his pledge against tax increases, saying they could support the Boehner plan B because it adhered to the meaning of their promise to oppose tax hikes. House Budget Chairman Paul Ryan, a leading conservative who was the Republican vice presidential nominee in the November election, will vote for Boehner's plan, a spokesman said Wednesday. Boehner and Republicans initially opposed any rise in tax rates but conceded to raising more revenue by eliminating some deductions and loopholes. The offer of a plan with higher rates for millionaires represented a further concession, but Obama and Democrats say it is not enough to ensure sufficient revenue from wealthy Americans as part of a deficit reduction package. Senate Majority Leader Harry Reid of Nevada said Boehner's backup plan appears to be a result of pressure from tea party conservatives opposing a wider deal. "It would be a shame if Republicans abandoned productive negotiations due to pressure from the tea party, as they have time and again," Reid said this week. He noted that the Senate passed a similar measure in 2010, and asserted that to oppose Boehner's plan now would make Democrats responsible for failing to avoid the fiscal cliff. While Obama's latest offer brought the two sides billions of dollars closer, it also generated protests from the liberal base of the Democratic Party because it included some benefit cuts in entitlement programs such as Social Security, Medicare and Medicaid.
