>> congress returns on monday in the u.s. senate will debate iran tension legislation. we learned more from a capitol hill reporter. rachel oswald is a national security reporter for "cq roll call." are these sanctions on iran new? and why do senators in both parties feel they're necessary now? rachel: these senators are coming after -- there was a big desire last year to impose sanctions. when, as you remember, iran carried out a spate of medium ballistic missile tests. president obama was in office at the time and he strongly pushed against democrats from pushing sanctions now. with him out of the office, that weight is now lifting. these are new sanctions. these are sanctions that would require the sanctioning of anybody directly and indirectly involved with iran's ballistic missile program. there are also new sanctions that would be imposed on the iranian revolutionary guard core

for their support of regionally destablizing activities and terrorism. host: in your recent article at cq.com on this iran sanctions bill that's coming up, you also write about a likely russian sanctions amendment, unrelated, that could come up as an amendment on this bill. why now? rachel: these sanctions are as a response to the 2016 election interference. democrats introduced a bill with considerable republican support back in january. and it's taken this long for them to build up enough support to move the sanctions forward. these sanctions would codify existing executive branch sanctions, making it difficult for president trump to remove the sanctions without the support of congress. they would also impose new sanctions attacking, forbidding any foreign investment in russia's energy sector, forbidding the sale of potentially -- purchases of iranian sovereign debt. and making it illegal to

purchase privatized russian -- former russian state assets. host: why would they be attached to this iran sanctions bill and not brought up as a separate measure? rachel: i think democrats saw an opening. when this iran bill was brought up and democrats -- there's enough support to clear a cloture vote for this bill. democrats saw an opportunity to has -- in order to get their support for the iran bill, to require republicans to at least allow a vote on the russia sanctions. host: lastly, in your cq article you write about senator corker likely being convinced to take up the russia piece to this. who's taking the lead on the democratic and republican sides? who is really pushing this russian measure? rachel: the leaders are benjamin cardin, armed services chairman john mccain, bob corker, and then from the banking committee, the chairman, mike crapo, and the ranking member, brown. host: rachel oswald covers national security issues for cq roll call.
