WASHINGTON -- The Latest on President Donald Trump and the shootings in Las Vegas (all times local):
The Senate has observed a moment of silence to honor victims of Sunday's mass shooting in Las Vegas.
Senate Majority Leader Mitch McConnell says "this is a moment of national mourning."
He says the mass shooting is shocking and tragic and devastating for the families of the victims.
McConnell says, "It's hard to even imagine their pain."
The Senate's tribute followed a moment of silence at the White House, where President Donald Trump paused on the South Lawn as a bell tolled three times.
At least 58 people were killed and hundreds others wounded in the shooting.
A bell tolled three times as a solemn President Donald Trump paused on the White House South Lawn for a moment of silence in honor of the victims of Sunday's mass shooting in Las Vegas.
Flanked by first lady Melania Trump, Vice President Mike Pence and his wife, Karen, Trump walked out onto the lawn for the memorial moment Monday afternoon. The White House's flag stood at half-staff overhead.
They were honoring the 58 people killed night when a gunman opened fire on a concert crowd in Las Vegas. Police say Stephen Craig Paddock was on the 32nd floor of the Mandalay Bay casino-hotel tower Sunday night when he fired into Route 91 Harvest festival. More than 500 people were wounded.
White House press secretary Sarah Huckabee Sanders says the day after the deadliest mass shooting in the nation's history is not the time to renew a debate over gun control.
Sanders was asked Monday during the press briefing that there is a "time and place" for a debate but that is "not the place we're in at this moment."
She said President Donald Trump was focused on the victims and stressed that it was a "time to unite the country."
Trump's predecessor Barack Obama frequently used mass shootings to call for stricter gun control laws. Trump did not mention firearms during his remarks earlier Monday after a gunman in Las Vegas and killed 58 people and injured at least 515 others.
The Republican president has cast himself as a friend to firearms owners and the powerful National Rifle Association lobby.
Former Rep. Gabrielle Giffords raised her fist at the Capitol and said "the nation is counting on you" after the deadly mass shooting in Las Vegas.
Giffords, who was grievously wounded in 2011, and her husband Mark Kelly were at the Capitol on Monday. They said the nation's thoughts and prayers are not enough and Congress must pass legislation to keep deadly weapons out of the wrong hands.
Kelly and Giffords had planned to campaign for Virginia gubernatorial candidate Ralph Northam, but instead they went to the Capitol to comment on the shooting.
Citing President Donald Trump, Kelly said "Americans need more than our president's prayers. We need his plans."
Kelly is calling for a commission to work on solutions to gun violence. He says it's the only acceptable moral course for the country.
President Donald Trump and the first lady will lead a moment of silence on Monday afternoon on the White House South Lawn to honor the victims of the deadly Las Vegas shooting.
Trump also spoke Monday with British Prime Minister Theresa May about the shooting. The White House says May conveyed her condolences after more than 50 people were killed and hundreds injured at an outdoor country music festival.
The White House says the president thanked May and praised the first responders in Las Vegas who responded to the shooting.
The CIA is advising caution on "jumping to conclusions" after the Islamic State group claimed responsibility for the Las Vegas shooting.
Agency spokesman Jonathan Liu says U.S. intelligence agencies are aware of the claim of responsibility. But he says people shouldn't rush to judgment "before the facts are in."
The CIA is deferring to law enforcement on the status of the investigation.
Without providing any evidence, the Islamic State group on Monday said the gunman in the mass shooting in Las Vegas was "a soldier" from its ranks who had converted to Islam months ago.
House Majority Whip Steve Scalise says he agrees with President Donald Trump that the mass shooting in Las Vegas that killed more than 50 people was "an act of pure evil."
Scalise, a Louisiana Republican, returned to the Capitol last week after he was shot and critically wounded in June as he and fellow Republicans practiced for a congressional baseball game. Scalise said he prays for the victims of the shooting and that the whole nation grieves with their loved ones.
Scalise encouraged people across America to stand together in solidarity to support the Las Vegas community, "especially by giving blood and encouraging others to do the same. In the face of unspeakable evil, our whole nation must respond with countless acts of kindness, warmth and generosity."
Democratic Sen. Chris Murphy of Connecticut says it's time for Congress to do something about mass shootings after more than 50 people were gunned down in Las Vegas.
Murphy, a leading gun-control proponent, said mass shootings had become an "epidemic" in America.
He said "it is positively infuriating that my colleagues in Congress are so afraid of the gun industry that they pretend there aren't public policy responses to this epidemic."
Other Democrats condemned the shooting but did not specifically urge gun-control legislation. Action in the Republican-controlled Congress is unlikely.
House Speaker Paul Ryan ordered flags over the Capitol lowered to half-staff and said "the whole country stands united in our shock, in our condolences and in our prayers."
The White House says that President Donald Trump has spoken to the Nevada governor, the Las Vegas mayor and the Las Vegas sheriff about the deadly mass shooting in Las Vegas.
