Debate over the border bill that was killed by Republicans in the House and Senate for political reasons continued on Tuesday when Sen. Chris Murphy (D-CT) called out Sens. Marsha Blackburn (R-TN), Ron Johnson (R-WI), and Tim Scott (R-SC) over their “bullshit” claims that President Joe Biden was responsible for closing the border himself.

First, Murphy went after Scott, who claimed on Fox News that “the left wants an open, insecure border.” In a post containing the video clip, he wrote: “Bullshit. We reached a bipartisan compromise to give the President enormous new powers to control the border. Almost every single Republican – including Sen. Scott – voted against it because Trump told them to keep the border a mess because it might help him politically.”

Next up was Johnson, who tweeted that “Americans want a secure border. The recent bill would have been worse than doing nothing by codifying @POTUS’s open border policies into law. We didn’t want an immigration bill. We wanted something to force Biden to use the authority he has to secure the border. Unfortunately, the secret negotiations led to a debacle that gave Democrats political cover for their open border policies.”

Again, Murphy responded: “Bullshit.” He added: “The bipartisan border bill that Sen. Johnson’s party asked for and then voted against because Trump said so would have ALLOWED THE PRESIDENT TO SECURE THE BORDER.”

Blackburn, who was a member of the bipartisan coalition in the Senate along with Murphy, posted on Twitter/X on Friday a harsh judgement on the Biden administration and impeached Homeland Security Secretary Alejandro Mayorkas, writing: “Even Secretary Mayorkas has said what’s happening at the southern border ‘certainly is a crisis.’ It’s past time the Biden administration put a stop to this madness. CLOSE the border.”

Murphy’s response to Blackburn’s claim: “[A]lso bullshit. Senator Blackburn knows the bill would have actually allowed the President to close parts of the border when crossings get too high. But who would book Republicans on cable news if the border was actually under control? That’s why they killed it.”

Blackburn worked on the bill herself and touted her own amendments to it, one of them being “Limiting the number of aliens who may be paroled into the U.S. each year.”
