The latest developments in the 2016 presidential campaign (all times EST):

8:20 p.m.

New Jersey Gov. Chris Christie isn't backing away when it comes to the hunting of black bears.

The Republican presidential contender was pressed at a New Hampshire town hall on his decision to authorize a bear hunt in New Jersey to control what he described as a ballooning population.

His response: "What's happens is New Jersey has been over-run by black bears. We've been over-run."

Christie boasted that the hunt killed more bears than ever before after he extended the hunting season.

Christie says a group of campaign workers at his headquarters in Morristown, New Jersey, went out for lunch recently and encountered a big black bear three blocks from the office, hanging out in a tree.

He says he has yet to consider his federal bear hunt policy.

6:50 p.m.

Florida Sen. Marco Rubio says if elected president he will advocate for the states to call a constitutional convention to impose term limits on members of Congress.

Rubio's comments are part of a pitch to rein in a federal government that he said is out of touch with regular Americans. He's also promising to repeal many of President Barack Obama's executive actions, including his upcoming actions on guns.

His remarks come during a campaign swing through New Hampshire, where he's holding three town hall meetings on Sunday.

Rubio says he'd use the bully pulpit of the presidency to support a constitutional convention to address three specific issues: term limits for members of Congress, term limits for federal judges and to pass a balanced budget amendment. He says creating term limits must come from a grassroots movement because members of Congress will never do it themselves.

5:25 p.m.

New Jersey Gov. Chris Christie is kicking off the new year in New Hampshire.

Christie on Sunday marked the opening of his second campaign office in the state — a cozy space in a strip mall next to a tattoo parlor in Salem.

Christie says that now that the holidays are over, voters are really starting to pay attention to their choices leading into the Feb. 9 primary.

He said: "This is now time for us to really put the pedal to the metal."

Republican voters, he says, are looking for "someone who's prepared and tested and mature and ready" to take on Democratic front-runner Hillary Clinton in the general election.

He's hoping voters decide that someone is him.

4:50 p.m.

Hillary Clinton is praising President Barack Obama's plan for new executive actions on gun control.

She says she's "hopeful and excited" that Obama's still-unannounced steps will curb gun violence.

She warns that a Republican president would reverse the president's steps "within the first day."

Clinton is making her first campaign appearance of 2016 with stops in New Hampshire.

1:20 p.m.

Hillary Clinton is denouncing the mass execution of 47 men by Saudi Arabia on Saturday.

The former secretary of state says the killings, which included the execution of a prominent Shiite Muslim cleric, "will inflame the region even more."

The majority of Muslims in Saudi Arabia are Sunni.

The Democratic presidential front-runner says the U.S. must raise some "serious questions" with the Saudi monarchy.

Clinton joins other international officials, including the White House, in criticizing the kingdom.

12:45 p.m.

Bernie Sanders generally passes up opportunities to take a dig at Democratic presidential rival Hillary Clinton. And he preaches the virtues of an issue-driven campaign. But Donald Trump clearly gets under his skin.

Sanders says time after time, the Republican front-runner "just comes up with things off the top of his head — that are lies."

And now the Vermont senator says Trump should stop talking about Bill Clinton's sexual history and start worrying about climate change, the minimum wage and tax breaks for rich people like Trump himself.

Trump says he brought up the subject because Hillary Clinton accused him of demeaning women. He accuses Bill Clinton of mistreating women and says his wife would "go along" with that. Sanders spoke Sunday on ABC's "This Week." Trump addressed the matter on "Fox & Friends."

12:15 p.m.

Carly Fiorina is branding Republican presidential rival Ted Cruz a typical politician who "says whatever he needs to say to get elected."

But the same critique has arisen about her, after she tweeted that she was rooting for the University of Iowa in the Rose Bowl against her alma mater, Stanford. In response, critics on Twitter called her out for pandering.

The former technology executive was asked about the tweet on CNN's "State of the Union" Sunday. She said it was tongue in cheek and asked, "Can't a girl ever have a little bit of fun? Stanford won the game 45-16.

As for Cruz, the Texas senator is taking more knocks these days because he's risen in polls in Iowa and elsewhere.

After a holiday-induced lull, the 2016 presidential campaign has come roaring back to life.

At least eight candidates appeared on the Sunday new shows, some pre-taped. And it's a busy day in New Hampshire, where Democrats Hillary Clinton and Bernie Sanders, and Republicans Marco Rubio and Chris Christie, are holding events. Donald Trump had a huge rally in Mississippi a day earlier.

Iowa is first in the nation to weigh in on the presidential nominations, with its caucuses on Feb. 1. Then comes New Hampshire on Feb. 9.
