Sen. Rand Paul has not held back in his criticism of fellow Kentuckian Mitch McConnell, accusing the Senate Minority Leader of "criminal neglect" in his handling of the southern border. 

During an interview on Fox Business Network’s Larry Kudlow on Friday, Paul weighed in on recent comments by Joe Biden that failing to provide another aid package to Ukraine amounts to a form of "criminal neglect." 

"The failure of the United States Congress, if it occurs, not to support Ukraine is close to criminal neglect," Biden said on Friday. "It is outrageous."

Needless to say, Paul did not agree.

“It’s criminal neglect for Mitch McConnell, Chuck Schumer, and Joe Biden to get together to send $100 billion overseas to fix someone else’s border before addressing our border.” 

He continued:

We have an emergency, we have an invasion. We have 700,000 people who came across in the last two months, and they’re willing just to punt on that. You know, they put forward a fake proposal, it wasn’t any good. We shot it down. But that doesn’t mean we’re ready to give up on it. Many of us want to fight. Thirty-two of us out of 48, three-fourths of us, said we wanted to keep fighting, and wanted to actually fix the border before we ship $100 billion of our money overseas.

I meet no one in Kentucky, no conservatives across the land for this, and the leadership of the Senate under Mitch McConnell is more concerned with sending your money to Ukraine than they are with the invasion of the southern border, and I’ve had enough. I’m going to do everything in my power to slow down and stop this, and I told them they can vote when hell freezes over because, frankly, this isn’t in the best interest of our country, and the money has to be borrowed. We don’t have $100 billion sitting around.

Despite refusing to support the recent bipartisan immigration bill, McConnell did agree to support sending additional aid to Ukraine for its war against Russia. 

Paul, meanwhile, declared that he would do everything he can to stop the sending of that money: 

[Ukraine aid] makes us weaker, it’s bad for the country. Mitch McConnell, Joe Biden, and Chuck Schumer are wrong on this, and I’m going to do everything I can to slow them down at the very least and possibly there’ll be enough of an uprising of people calling in and saying, ‘Mitch McConnell, who are you? Do you represent the Republicans, do you represent conservatives, are you in lockstep with Chuck Schumer?’ There needs to be an uprising in the country, and if that happens, we still have a chance we can stop this.

Despite being a supporter of legal migration, Paul is among the many Republicans sounding the alarm about the crisis at the southern border, where hundreds of thousands of people are passing through illegally every month.

In an interview with conservative commentator Dave Rubin earlier this week, Paul pointed out that the long-term objective of Democratic support for illegal immigration is the belief that it will allow them to finally take Texas from the Republicans and build a national supermajority: 

"Their whole goal is to take Texas," he explained. "They've been trying to take Texas for 20 years. The only way they take Texas is to legalize a couple of million people here illegally and let them vote, the sooner the better."
