The Obama administration is pulling out all the stops to try to convince lawmakers in its own party that its new deal with Iran, is a good deal.
The state department said Tuesday that Secretary of State John Kerry is sending a video to all members of Congress in which he outlined "in very basic terms" what the Iran deal does and what it doesn't do.
Secretary Kerry is also making phone calls to his former colleagues to try to convince them to give his diplomacy a chance.
Lawmakers - including Senate Majority Leader Harry Reid - still intend to consider possible new sanctions against Iran right after the administration agreed to loosen sanctions, in exchange for temporary restraint on Iran's nuclear program.

Iran lashes out - rejecting the U.S.'s interpretation of the nuclear deal.
According to a spokeswoman for Iran's Foreign Ministry, "What has been released by the website of the White House as a fact sheet is a one-sided interpretation of the agreed text in Geneva ... which is not true."
At the same time, Secretary of State John Kerry is going on a full court assault to sell the deal's talking points to his own party - sending them a video outlining what it's in the deal, and calling for one-on-one consultations.
So what does the Obama administration think about Iran's accusation it is "lying"?

President Obama is praising the deal reached this weekend between Iran and world powers over the country's nuclear program.
During a speech on immigration Monday, Obama told the crowd, "For the first time in a decade, we halted the process on Iran's nuclear program; key parts of the program will be rolled back."
As part of the deal, Iran agreed to limit its nuclear program and in exchange, the U.S. agrees to ease sanctions.
The agreement is being seen as a huge win in Iran. Iranians celebrated the deal, which allows them to keep enriching uranium, Sunday night.
Is the deal a giant fail for America? A big win?
That comes down to one thing: whether the U.S. can guarantee Iran is keeping its end of the bargain and that means real, unfettered inspections.

Western diplomats and Iran may be nearing a deal on the country’s nuclear program.
The agreement is so close, Secretary of State John Kerry cut short a trip to the Middle East to join the negotiations – an unprecedented move.
The emerging deal would ease some sanctions against Iran and, in exchange, Iran would stop enriching uranium to a level required for nuclear power or a potential weapons program for a few months.
The United States' closest ally in the Middle East isn't on board though.
Israeli Prime Minster Benjamin Netanyahu says “Iran got the deal of the century” and calls this “a very bad deal.”
Congressman Eliot Engel, the senior Democratic member on the House Foreign Affairs Committee, is OutFront with his take.
Israeli Prime Minister Benjamin Netanyahu called out his Iranian counterpart again and again with the hopes of shredding Hassan Rouhani's credibility when it comes to Tehran's claim that it wants to process yellowcake uranium to make fuel - not weapons.
"It's not hard to find evidence that Iran has a nuclear weapons program," Netanyahu said. "It's hard to find evidence that Iran doesn't have a nuclear weapons program."
