Is there an unfair crusade going on against the famed cyclist and former cancer patient Lance Armstrong, who is facing renewed allegations of doping?

The debate is flowing across the Internet and on Wednesday, Howard County Executive Ken Ulman, whose brother, Doug Ulman, is the CEO of Armstrong's cancer charity Livestrong, weighed in from his Facebook page.

“Let's focus on what matters most for our nation & not continue to chase a man who has done more in the fight against cancer than anyone else,” Ken Ulman posted to his public Facebook page on Wednesday night.

Armstrong, 40, has denied allegations of using performance enhancing drugs and participating in a “doping conspiracy.” He was formally charged by the U.S. Anti-Doping Agency and faces losing his victories as a seven-time Tour de France winner, according to an Associated Press story on the Huffington Post.

On his Twitter page, Armstrong called the agency’s move a “witch hunt.”

“I have never doped, and, unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one,” Armstrong said in a statement.

Armstrong is also a testicular cancer survivor who formed the Lance Armstrong Foundation to help others struggling with cancer.

Doug Ulman is a three-time cancer survivor and is the president and CEO of Livestrong, Armstrong's cancer charity.

He and his family also founded the Ulman Cancer Fund for Young Adults, a Columbia-based nonprofit that helps young adults affected by cancer and their families. 

The USADA is accusing Armstrong of “using and promoting the use of the blood booster EPO, blood transfusions, testosterone, human growth hormone and anti-inflammatory steroids,” according to a copy of an agency letter obtained by the Associated Press.
