I’ve been standing outside the Senate floor as lawmakers voted for the first time since President Donald Trump has taken the oath of office.
Many are keeping quiet on some of Trump’s day one actions and where they stand when it comes to ing Trump’s cabinet picks.
One Republican senator, Susan Collins of Maine, says she’s still deciding whether she will Secretary of Defense pick Pete Hegseth’s confirmation.
Hegseth has become one of Trump's most controversial choices, having faced allegations of sexual assault. He has repeatedly denied any wrongdoing.
Alaska Senator Lisa Murkowski, also a Republican, told a large gaggle of reporters that she wouldn’t comment on any of the nominees.
Senator Richard Blumenthal, a Democrat from Connecticut, raised concerns over whether Trump’s nominees will stand up to the president if he asks them to do something unconstitutional.
He said he believes Marco Rubio, who he voted to confirm as secretary of state a short while ago, would stand up to Trump. “I know him,” he said.
When asked if there are any other nominees Blumenthal is planning to , he responded: “I’m not sure yet.”
All day we've been awaiting potential immigration action from President Donald Trump, after he declared a national emergency at the US-Mexico border in his first speech of the day.
Here's a look at how that anticipation has been playing out at the US-Mexico border.

There have been cheers as they heard the news they were hoping for, as President Donald Trump told the crowd at the Capital One arena that he would soon be g pardons for the 6 January "hostages" when he gets to the Oval Office.
"Freedom!" shouts one woman.
People here believe that as soon as those pardons are signed, defendants could be walking out of the jail gates within a few hours.
Trump has characterised those jailed for the attack on the Capitol as "political prisoners" and he had promised to grant pardons, though it has not yet been made clear how far these will go, and whether it will also include those convicted of violent assaults.
"We're going to release our great hostages… that for the most part, didn't do a lot wrong," Trump told the arena crowd.
Meanwhile, critics say that pardoning riotors sends the wrong message, and will be seen as a betrayal by many police officers who were injured that day.

The Senate has confirmed Marco Rubio to serve as secretary of state.
Rubio was unanimously confirmed by a vote of 99-0.
He just exited the Senate floor, telling reporters he feels “good” about his confirmation and that it’s a “great honour".
This is the first Trump cabinet official to be approved for a role.

Donald Trump took an ordinary presidential act – rescinding orders from a previous istration of different party – and turned it into spectacle.
After giving another winding speech – his third of the day – Trump moved to a small desk on the stage at the downtown sport arena where his indoor inaugural parade had just concluded. Then he went to work freezing new federal regulations and hiring, reversing Biden istration directives, mandating federal workers work in-office full-time and withdrawing from the Paris Climate Accords.
“Can you imagine Joe Biden doing this?” he asked after g the regulation freeze – but that could have applied to visuals of the moment as much as to the content of the orders.
He also signed more symbolic orders to end the “weaponisation of government” and instruct his istration to address the higher cost of living.
It’s just the start of what promises to be a record number of first-day executive actions, including a promised pardon of many of some who participated in the 6 January attack on the US Capitol.
After the arena ceremony, Trump tossed the pens he used into the crowd – another Trumping flourish.
Trump has just signed a number of orders in front of his ers inside the arena in Washington DC.
This is the list as it was described to the arena:
Watch: President Donald Trump signs first executive orders in arena

Donald Trump entered the arena brandishing a binder, waving it around and pointing to it - a binder that contained the various executive orders and actions he had brought to sign in front of this crowd of 20,000 ers.
After his Middle East Special Envoy Steve Witkoff introduced some of the families of the hostages held in Gaza - some of whom already know their loved ones are dead - and others who still have relatives being held, Trump told the crowd he'd be g orders in the Oval Office later tonight pardoning what he described as the 6 January "hostages" - many of whom are actually convicted criminals - for their part in the riots at the Capitol four years ago.
Among the plans he highlighted was his insistence that his whole cabinet would have to "marshal every hour to bring down inflation" - though just how he wasn't saying.
He also said he would sign measures to end the "weaponisation" of the justice system, something he believes he's been the victim of for years.
He signed nine items in all including a document withdrawing the US from the Paris climate treaty - which he did before at the beginning of his first term.
It was a piece of theatre the crowd loved - all topped off, of course, with the Trump anthem, YMCA, playing from the speakers.
The crowd chants "USA, USA" as Donald Trump departs the stage with Melania.
JD Vance and his wife follow.
The president is now expected to head to the White House, and the YMCA - which has become a Trump campaign anthem - fills the arena.

He promises the crowd he will sign many more when he returns to the Oval Office and begins throwing pens up in the air to the crowd.
The arena hears the next action Trump is g relates to a "regulatory freeze preventing bureaucrats from issuing anymore regulations" until the istration has full control of the government.
The President signs it and holds it up.
He then does the same for an order that is introduced as a freeze on federal hiring, excepting the military, and a number of other excluded categories, again until "full control" of the government is achieved.
Each g is getting large cheers.
"Could you imagine Biden doing this? I don't think so," Trump says.
Image source, ReutersDonald Trump has started g a number of executive actions.
The first one is rescinding 78 Biden-era executive actions.
Trump signs the action and holds it up to the crowd as they cheer.
Trump tells the arena "you're going to watch a lot of good things happen".
"We're going to stop some wars," Trump says, suggesting the conflicts in Ukraine and Gaza would not have happened if he had been in power.
Trump is speaking now about his plans for the 6 January "hostages" as he describes them - referring to those imprisoned as a result of the 2020 Capitol riot.
He has been teasing for days now that he would pardon individuals convicted of wrongdoing during the riot in 2021.
He's telling the crowd they didn't do anything wrong.
At the arena, Trump says he is going to end what he describes as the "weaponisation" of the justice system, referring to "these creeps".
"I've been investigated more than any human being in the world," he says.
The president then criticises his predecessor Joe Biden for pardoning of his family before leaving office. "Can you imagine that">Earlier today Biden pre-emptively pardoned several family , including his brothers James and Frank Biden, and sister Valerie Biden Owens, saying the pardons were intended to shield them from politically motivated attacks and should not be mistaken as an acknowledgment of any wrongdoing.

The president says Barron Trump "knew the youth vote", which helped him win the election.
President Trump's granddaughter, 17-year-old Kai Trump, who is popular on YouTube and TikTok, is also presented as someone who is a young, influential part of the Trump brand.
Trump is speaking about tariffs, a popular topic of conversation for the president.
"Tariffs are going to make us rich as hell," Trump says to loud applause.
Trump tells the crowd God is first, religion is second, love is third and tariff is fourth in of the most beautiful words in the dictionary.
He tells the crowd he will sign an executive order on free speech.
Throughout the campaign, Trump had promise to slap heavy tariffs on Mexico, Canada and China on day one of his istration.
But Trump officials told US media on Monday that he would issue a broad trade memorandum that stopped short of immediately imposing tariffs and instead focus on investigating US trade relationships with those three countries.
