Political career
Elkin was elected to the 17th Knesset in 2006 as a member of Kadima and chaired the subcommittee on the absorption of immigrant children and youth. In November 2008 he decided to quit Kadima, as he considered it to have become a left-wing party. He subsequently joined Likud, and won twentieth place on its list for the 2009 elections. He retained his seat as Likud won 27 mandates. In November 2012, he released an election video for his Likud primaries campaign that went viral, earning 250,000 views in only a matter of days. He was subsequently re-elected again in 2013. He served as Deputy Minister of Foreign Affairs between March 2013 and June 2014, and then became Chairman of the Knesset's Foreign Affairs and Defense Committee. Elkin was placed eighth on the Likud list for the 2015 elections, and was re-elected when Likud won 30 seats. After the elections, he was appointed Minister of Immigrant Absorption and Minister of Strategic Affairs in the new government. Elkin surrendered the Strategic Affairs post after only 11 days, when Prime Minister Netanyahu appointed Gilad ErdanMinister of Public Security, Strategic Affairs, and Public Diplomacy on 24 May 2015. Elkin demanded the Minister of Jerusalem Affairs portfolio as compensation for losing Strategic Affairs. Netanyahu met his demand, breaking an election promise to the Mayor of Jerusalem, Nir Barkat, who had wanted Netanyahu to retain the portfolio himself. On 30 May 2016, Elkin lost the portfolio of Minister of Immigrant Absorption to Sofa Landver of Yisrael Beiteinu. However, on 1 August 2016, he was appointed Minister of Environmental Protection, succeeding Avi Gabbay.
