The measures were introduced following a 15-hour talk-a-thon in which Democrats demanded new controls on gun sales following the shootings in Orlando, Fla.

Just over a week after the deadly nightclub rampage in Florida, the Senate has voted down measures to expand background checks and limit purchases by those on terrorism watch lists.

The outcome of Monday's gun legislation votes may surprise no one, but some Senate Democrats are convinced their talk-a-thon has prompted colleagues on the other side to brainstorm workable solutions.

The mass shooting at a gay nightclub in Orlando, Fla., has reignited calls on Capitol Hill for tighter gun laws.

Bernie Sanders pledged to work with Hillary Clinton to defeat Donald Trump. But later on Thursday at his last rally of the primary season, he carried on as if determined to become the next president.

It's getting awkward in the Senate, where members go out of their way to avoid directly chastising each other. The low-simmering annoyance with Sanders for staying in the contest is palpable.

The Massachusetts senator has become one of the most aggressive anti-Trump voices in her party. But inside the Senate hallways, she doesn't behave like a woman who wants to be heard.

Garland was approved for confirmation to the U.S. Court of Appeals in Washington, D.C., by the Senate in 1997, and he is widely viewed as a moderate. Senate Majority Leader Mitch McConnell repeated his pledge that the Senate would not take any steps toward confirming Obama's nominee, setting up a judicial confirmation fight that will now take center stage in the current election drama.

The relationship between President Obama and Senate Majority Leader Mitch McConnell the last 7 years has been often confrontational and awkward, marked by occasional bouts of productive deal-making.

The Republican presidential candidate hadn't received a single endorsement from his Senate colleagues until this week.

Every Republican on the Senate Judiciary Committee has signed a letter pledging they won't hold any hearings on any Supreme Court nominee President Obama names this year.

When Congress returns from recess next week, it will be the first time since Justice Antonin Scalia's death for Senate Republicans to hash out face-to-face exactly what they're going to do about the newest Supreme Court vacancy.
