48 hours ago has already hit a legislative wall.

Senate Republicans today announced they will block## the long-negotiated proposal that would# address th aid to Ukraine and Israel.

The bill drew# sharp opposition from House Republicans,## who spent much of today debating whether# to impeach the homeland security secretary.

Congressional correspondent Lisa# Desjardins and our team have been## working sources in both chambers.

She joins# us now live Lisa, this bill has not even been debated.

The# debate hasn't even begun over the border deal.## Republicans are blocking it already.

Why# is that?

And also how final is that block?

LISA DESJARDINS: This is a real# moment of logical disconnect.

It does seem that the votes technically# are ther but when Senate Republicans met behind# closed doors last night and today, they## decided they would not support actually opening# up this bill.

There are a few reasons for that,## and part of it has to do with the# pressure on them over the border.

A lot of it has to do with election-year politics.# There is a debate still over th of the border crisis itself, but when it comes# to the reasons that this bill offering a solution## was pulled, Republicans today looked at each# other and sort of blamed each other for it.

SEN. RON JOHNSON (R-WI): We wanted to secure# the border.

That is why we are voting no.

This## does more harm than good, and that's not James# Lankford's fault.

That's SEN. MITCH MCCONNELL (R-KY): Things# have changed over the last four months,## and it's been made perfectly clear by the speaker# that he wouldn't take it up even if we s him.

And so I think that's probably why most of# our members think we ought to have opposition.

REP. MIKE JOHNSON (R-LA): They did not send# us a border security measure.

They didn't.## They sent us a supplemental funding# proposal that has immigrat but not real border security reform,# and so that's why it's a nonstarter.

LISA DESJARDINS: A waterfall of blame here,## some blaming McConnell, But, clearly, there is something else# at work here.

Democrats, for their part,## including President Biden, say# what happened is much more simple.

JOE BIDEN, President of the United# States: All indications are this## bill won't even move f Donald Trump.

Because Donald Trump# thinks it's bad for him politically.

He'd rather weaponize this# issue than actually solve it.

LISA DESJARDINS: Now, there is not# a plan B for either how to deal with## the border crisis or for Ukraine# funding.

The House tonight may## take a vote on a separate bill on# Israel funding.

That may not pass.

So we're not clear what# happens on any of these issues,## if there can be progress on any# of them in coming da AMNA NAWAZ: Lisa, meanwhile, as# we mentioned earlier, a rare vote## planned in the House today to impeach the# Department of Alejandro Mayorkas.

Where does that stand?

LISA DESJARDINS: Amna, this is incredibly close.

I am speaking to you at the exac House Republicans even bring up this vote.# They have teed it up.

This is vo te closing out now.

They are expected# to bring up this impeachment vote next.

But I have to tell you, from my reporting Amna,# I don't think House Republicans have the vote,## the majority vote, to pass it.# As we have said on this program,## there is an incredibly narrow margin# in the House for Republica can lose only two members and pass# things with only Republican votes.

We know of at least two members# who are against this.

And, today,## the National Fraternal Order of Police came# out with a letter saying th eir view has actually helped things, that# he is someone who respects law and order.

Now those Republicans who want to impeach him say## instead that Mayorkas has had a willful# th ey say he lied to Congress as well.

Mayorkas# denies that.

He says this is political.

A real test for House Republicans in a major## effort tonight.

We should know in# the next hour or so what AM NA NAWAZ: That's congressional correspondent# Lisa Desjardins with the latest on C Lisa, thank you.
