The 1996 Iran Sanctions Act (ISA) gives the president the authority to impose sanctions on Iran and needs to be continuously renewed by Congress. The legislation introduced Monday, the Solidifying Iran Sanction Act, would get rid of the ISA's sunset clause.

In the House, the bill was introduced by Rep. Michelle Steele (R-CA) and so far has 24 cosponsors, including 16 Republicans and 8 Democrats. Rep. Michael McCaul (R-CA), chair of the House Foreign Affairs Committee, is one of the cosponsors.
