AMNA NAWAZ: For U.S.

senators, today was# the first full day back in Washington after## the killing of Alex Pretti and ahead# of their Friday deadline to fund the## Department of Homeland Security and some# of the government's other large agencies.

They arrived as news is still unfolding on the## Pretti shooting and as another# lawmaker faced a new threat.

Our congressional correspondent, Lisa# Desjardins, joins me now for more on all of this.

So, Lisa, we have been covering the# outrage after the Pretti shooting,## the sense that something# shifted.

As you talk to senators,## are you sensing a shift in how they're# viewing the immigration crackdown?

LISA DESJARDINS: We did.

We have# been watching that carefully.

And, today, I have to tell you we heard# from Republicans a new kind of very open## sense that federal enforcement officers# went too far in a dangerous way.

Now,## some of them word this carefully, but, more,# we are seeing Republicans say this sharply.

That includes Homeland# Security Chairman Rand Paul.

SEN.

RAND PAUL (R-KY): We can't just# say, oh, nothing to see here, and he## was obviously an assassin and a domestic# terrorist.

When we say things like that,## it leads to no confidence in -- so I think there# really has to be an independent investigation.

And this is going to be an investigation# outside of DHS.

They should themselves## immediately appoint a commission.

If# they don't, I think Congress may do it.

LISA DESJARDINS: So there we# go, a commission potentially.

Now, Rand Paul is known to break with# President Trump, but I heard this kind## of idea, concern from more Republicans# who don't usually do that.

Of course,## for Democrats, it's more than just concern.

An example is this from Senator# Cory Booker of New Jersey: SEN.

CORY BOOKER (D-NJ): This agency is out of# control.

Its leadership is out of control.

Its## leadership should step down, if not be impeached.# So we are in a serious, serious crisis right now.

LISA DESJARDINS: And there# are calls to impeach Kristi## Noem.

We're going to be talking# more about that in coming days.

But I want to also point out one other group# of Republicans.

These are Republicans who say,## even as they express some concern about# ICE, that they think protesters are being## too aggressive.

One example of# that is Florida's Rick Scott.

SEN.

RICK SCOTT (R-FL): You have a# right to protest in this country,## but you don't have a right to interfere with# law enforcement.

So don't be stupid.

Don't## interfere with law enforcement.

We all are going# to have to work together to get the criminals out## of our country.

Local law enforcement should be# working to work hand in glove with ICE right now.

LISA DESJARDINS: One other standout# note, Republican Leader John Thune## told reporters he thinks this is in# fact potentially an inflection moment.

AMNA NAWAZ: So, when it comes to leaders who have# concerns about the tactics of federal agents,## especially Democrats, what are they# going to do about ICE and what does## this mean for the chance of a potential shutdown?

LISA DESJARDINS: Those are intertwined questions.

And let's start with Democrats.

Many people# have been wondering.

Senat.. told reporters what Democrats want to fund DHS.# There are three things that he listed today,## first, that they would end roving# raids, enforce code of conduct,## and hold agents accountable for harming# people, and also that there would be no## more masking, that they would require# bodycams and I.D.s on all officers.

But the problem is, the DHS funding bill,# of course, already passed the House,## along with all these other funding bills.

So to# change it now would cause that partial shutdown.

The White House says, if Democrats# demand a legislative fix, there will## be a shutdown.

And that's the point we're# at right now.

One difference, though, is,## people seem to want a solution, but, honestly,# they're just far apart on how to get there.

AMNA NAWAZ: So let's leave Washington# for just a moment and talk about this## climate of political violence I know# you spend a lot of time covering.

Another attack on a member of Congress.

This time,## it was Democrat Ilhan Omar last# night.

Bring us up to speed.

LISA DESJARDINS: Viewers may know# Omar represents Minneapolis.

She## herself is a Somali immigrant.

She also is# someone who has really received the most## vitriolic rhetoric from President# Trump while he's been in office.

She was speaking at a town hall in# Minneapolis last night when a man## ran toward her.

He squirted a syringe with# an unidentified liquid.

And a reporter said## there was a vinegar smell afterward.# Police have arrested a man who the## Associated Press said supported Trump# online and also called Democrats liars.

As for Omar, she kept going at that town hall.# And she posted some defiance on social media,## writing that: "This small agitator isn't going## to intimidate me from doing my# work.

I don't let bullies win."

But President Trump was asked about this.# He told ABC that he didn't watch the video,## but he called Omar a fraud.

He gaslit her,# saying she probably had herself sprayed.

Now, we raise that because that's# a message, even if it is a joke,## that is part of this climate of intimidation.

AMNA NAWAZ: Meanwhile, we know there's# some new information about the level of## threats against lawmakers.

What# should we understand about that?

LISA DESJARDINS: Capitol Police came out with some## eye-popping statistics over the number# of threats t.. Let's take a look at this.

It came out just# yesterday, last night.

Look at this.

These are## the number of threats that Capitol Police# have investigated in the last few years.

And you see that spike?

That is last# year, 14,000-plus threats against## members of Congress investigated.

Amna,# that's more than a 50 percent increase## from the year before.

So they do# have more funding for security.

But I can tell you personally# lawmakers are feeling this,## some of them having to move their# residence, taking careful plans## with family vacations.

This is a real# climate of political violence and threat.

AMNA NAWAZ: Lisa Desjardins, thank you, as always.

LISA## DESJARDINS: You'..
