Former US Senator Tom Coburn, 72, died early Saturday morning after a long fight with prostate cancer, according to a statement from his family.
Coburn served in the Senate from 2005 to 2015 and in the US House of Representatives from 1995 to 2001. After retiring from the Senate, he pushed for a constitutional convention and stood up for a range of conservative fiscal causes.
Lawmakers and senators have remembered the prominent senator and expressed their condolences to his family on Twitter.
US Vice President Mike Pence has also sent his sympathies to Coburn's family on Twitter.
Coburn had several health problems during his time in office. He was treated for malignant melanoma in 1975, and he underwent surgery for prostate cancer in 2011.
