House Speaker John Boehner will give up his seat in Congress at the end of October.
Boehner became the 53rd speaker of the House in 2011. The Ohio Republican's tenure has been marked by fierce confrontations with Democrats and sometimes with his own party. One of those fights led to a 16-day partial government shutdown in 2013.
Amid renewed conflict with more conservative members of his party, Boehner is once again facing the prospect of a government shutdown.
