Sen. Rand Paul (R-KY) is "unsure" whether or not he has signed up for insurance under the health care law.

"I'm trying to pay for insurance and can't pay for it. And I'm uncertain now whether I'm enrolled DC and/or Kentucky," he said Sunday on ABC's "This Week." "And it's a mess."

Senate Majority Leader Harry Reid (D-NV) on Sunday said that he is not currently planning to entirely eliminate the filibuster from Senate rules.

"We're not there yet," he said on CBS' "Face the Nation." "I'm not thinking about it today."

Sen. Chuck Schumer (D-NY), the No. 3 Democrat in the Senate, on Sunday said he was optimistic that enough House Republicans will support immigration reform to pass legislation in 2014.

"I think that it's likely we will get immigration reform this year," he said on ABC's "This Week." "There are large parts of the Republican Party, even conservative parts of the Republican Party, that want this -- business, Evangelical churches, the Catholic Church, high tech, growers. So it's not like some of the budget issues where all of the Republicans are on one side."

Sen. Rand Paul (R-KY) on Sunday suggested that former National Security Agency contractor Edward Snowden and Director of National Intelligence James Clapper should share a prison cell in the U.S.

"Maybe if they served in a prison cell together, we'd become further enlightened as a country over what we should and shouldn't do," he said on ABC's "This Week."

Senate Majority Leader Harry (D-NV) on Sunday said he was worried about Congress' ability to agree to a debt ceiling increase.

"I'm afraid," Reid said on CBS' "Face the Nation" about Congress' need to raise the debt limit at some point in February or March.

Senate Majority Leader Harry Reid on Sunday said that in order for the government to extend longterm unemployment benefits, Republican lawmakers need to stop being themselves.

Reid said that the "vast majority of American people," including conservatives, support extending unemployment insurance, but that GOP lawmakers do not.

Sen. Rand Paul (R-KY) on Sunday said he could support extending the longterm unemployment benefits that expired at the end of 2013 if the program is paid for.

"I'm not against having unemployment insurance," he said on ABC's "This Week." "It needs to be payed for."

Former GOP presidential candidate and Massachusetts Gov. Mitt Romney on Sunday said he wished he could go back in time when asked about Obamacare and the 2012 election.

"I don't know. I wish I could go back and turn back the clock and take another try," he said on "Fox News Sunday" when asked if he felt he would have won the 2012 election if President Obama had not told Americans that they would be all able to be able to keep their current plans under the health care law -- a claim that in many cases turned out not to be the case.

Mitt Romney on Sunday said he accepted MSNBC host Melissa Harris-Perry's apology for a controversial segment on her show poking fun at a Romney family photo including Romney's African-American adopted grandson, Kieran Romney.

"I think her apology was clearly heartfelt, and we accept that," former Massachusetts Gov. and GOP presidential candidate Mitt Romney said on "Fox News Sunday." "I've made plenty of mistakes myself, and they've apologized."

Only 26 percent of uninsured Americans have visited a health care exchange website, according to a December Gallup poll released Thursday.

Still, the December numbers show a slight uptick from 20 percent in October and November, and Gallup noted that the December poll numbers could underestimate how many people actually visited an exchange website.
