Vice President Joe Biden Thursday slammed President Donald Trump for his efforts to repeal the Affordable Care Act, a move that he said would eliminate health care for 11.5 million Texans with pre-existing conditions.

“With each passing day, Donald Trump makes it clearer and clearer that he is the most corrupt president in modern American history,” Biden said in a statement released to The Dallas Morning News. “But even as he shoots holes in the Constitution and commits impeachable offenses, we cannot let him off the hook for sabotaging the health care of millions of hard-working families.”

Biden released his statement hours before Trump’s rally in front of thousands of people at American Airlines Center.

The frontrunner in the Democratic Party race for president has been sparring with Trump for months, most recently over the impeachment inquiry against Trump, who asked a new president of Ukraine to investigate Biden and his family.

Most of Biden’s statement Thursday was related to health care.

“Trump has spent his entire presidency attempting to sabotage and repeal Obamacare, which would eliminate protections for the 11.5 million Texans with pre-existing conditions,” Biden said. “That’s almost half of all Texans.”

“As Trump takes the stage tonight to spew lies, embrace hate, and divide the country, Texans must remember that Trump has stood shoulder-to-shoulder with Texas Republicans who have blocked Medicaid expansion under the Affordable Care Act — instead choosing to actively withhold health care from nearly 1.5 million eligible Texans.”

Biden said his health care plan would build on the existing Affordable Care Act.

Former Rep. Beto O’Rourke, Biden’s rival in the Democratic race for president, is staging a Trump counter-rally at the Theatre at Grand Prairie.
