Nadda was first elected to the
Himachal Pradesh Legislative Assembly in the
election of 1993 from
Bilaspur. He was
re-elected in 1998. During his first term, he served as the Leader of his party group in the Himachal Pradesh Legislative Assembly from 1994 to 1998. He was the Minister of Health and Family Welfare and Parliamentary Affairs in
First Dhumal ministry. Nadda lost his seat in the
2003 Himachal Pradesh Legislative Assembly election. Nadda was elected for another term in the
2007 elections. After
Prem Kumar Dhumal formed a government, he inducted Nadda into his cabinet, as a cabinet minister responsible for Forest, Environment, Science and Technology, from 2008 to 2010. As a result of Chaturvedi's investigations, the CBI registered cases and recommended action against Vineet Chawdhry, a close aide to Nadda. In 2014, Nadda wrote multiple letters to the then Union Health Minister,
Harsh Vardhan, to put the investigations on hold and to remove Chaturvedi from the post of CVO. In November 2014,
during a cabinet reshuffle, Prime Minister
Narendra Modi made Nadda the
Minister of Health. The reshuffle move was described by a section of media as surprising and something which raised questions on Modi's stance on corruption. On 25 February 2015, the
Delhi High Court issued a notice to Nadda questioning his role in corruption cases at AIIMS. According to a June 2017
India Today investigative report, Nadda was found to have suppressed an investigation of what the report called a ₹7,000 crore scam. The
India Today reports included reports from the
CBI and a parliamentary committee. == President of the Bharatiya Janata Party (2019–2026) ==
