It's not yet clear how much they are looking to change.
Earlier this week, the Senate came together and overwhelmingly passed a bill that would impose new sanctions against Russian Federation and allow Congress to review any attempts by the president to lessen them. Dan Fried, who retired in February as coordinator for sanctions policy at the State Department, told Yahoo News that there was "serious consideration" by the Trump White House to "unilaterally rescind the sanctions".
However, with the bill heading to the House, it appears that the White House is now working with House Republicans to weaken the legislation and restore President Donald Trump's power over the sanctions.
The bill, which passed 98-2, targets Russian individuals accused of corruption and key sectors of the Russian economy. Mike Crapo (R-Id.) on the floor of the Senate on June 13, aside from codifying existing sanctions, the amendment also attacks Russian economic activities in gas and oil production, railway, shipping and metals and mining. During that process, the sanctions will remain in place unless the Congress votes in agreement with the President.
Rubio: Trump firing Mueller 'not going to happen'
But Mr Rosenstein, too, may ultimately have to end his oversight, given his role in Mr Trump's decision to fire Mr Comey. Trump has repeatedly tweeted about the Russian Federation investigation, last week calling the probe a "witch hunt".
A senior administration official said the White House is unhappy with measures in the Senate bill created to limit Trump's ability to ease the sanctions without congressional approval.
In other words, the Trump administration may (again) be betting that loyalty to the president - or more likely, fear of his political base - will be more important to House Republicans than the omnipresent suspicions over, and investigation into, possible ties between the Trump campaign and Russian Federation, as well as the president's seeming attempts to dismiss that investigation.
In a state-television interview which aired Saturday, Russian president Vladimir Putin said that the proposed sanctions were "harmful" and would "complicate Russia-American relations".
