Former Vice President Joe Biden on Tuesday night said the Trump administration was not interested in prioritizing fighting cancer after he asked the White House to build off the work he and former President Obama began.

Biden, who is expected to jump into the Democratic presidential primary in the coming weeks, discussed reaching out to the Trump administration after the 2016 election to encourage it to expand on the 2016 national “Cancer Moonshot” initiative.

Neither a Biden spokesperson nor the White House responded immediately to requests for comment from The Hill.

Biden has been a leading advocate of expanding funding for cancer research since he lost his son Beau to cancer at the age of 46 in 2015. He has since founded the Biden Cancer Initiative and called fighting cancer “the cause of my life.”

“We can, must and are able to do something about it. It’s within our power,” Biden said.

Biden has emerged as a staunch critic of Trump, at one point saying during the 2016 election that “if we were in high school, I’d take him behind the gym and beat the hell out of him.”

However, his own presidential aspirations hit a snag in recent weeks after several women accused him of inappropriate touching.
