Today's installment of campaign-related news items from across the country.
* In New Hampshire, a new Monmouth poll shows Bernie Sanders continuing to lead Hillary Clinton, 53% to 39%.
* Given Hillary Clinton's recent focus on guns, the Democratic candidate was no doubt pleased to pick up an endorsement from the Brady Campaign to Prevent Gun Violence.
* Given Bernie Sanders' focus on progressive activism, the Democratic candidate was no doubt pleased to pick up an endorsement this morning from MoveOn.org.
* Marco Rubio originally planned to skip a classified briefing on North Korea yesterday to attend a Florida fundraiser, but he changed his plans after less-than-flattering news reports about his schedule. The senator reportedly attended the briefing for about 20 minutes before leaving early -- and avoiding reporters waiting outside.
* Just when it seemed things couldn't get worse for Ben Carson's campaign, the Republican candidate's general counsel and operations director have also quit Team Carson.
* And speaking of candidates losing top staffers, Rand Paul's foreign policy aide, Elise Jordan, has left the senator's campaign team. She'll now be a political analyst for NBC News and MSNBC.
* It's not just Marco Rubio's team going after Chris Christie in New Hampshire; Jeb Bush's super PAC has begun slamming the New Jersey governor in direct-mail pieces sent to Republicans in the Granite State.
* And in a curious move, Pennsylvania Attorney General Kathleen Kane (D) apparently intends to run for re-election, despite the fact that she's currently under criminal indictment.
