The firm had a website "but it had no depth to it, and there was no detailed information about the 'U.K. person'" who had written the e-mail, he said.
"Face the Nation" moderator Margaret Brennan reports the U.S. and its European allies would create a proposal that addresses Mr. Trump's concerns about the agreement - ballistic missiles, military site inspections and the sunset clause - thus allowing Mr. Trump to claim he "fixed" the 2015 international agreement without actually altering a word of the agreement and without Iran's consent. He has several options, so the fallout either way is not yet clear.
Rouhani said that only three countries oppose the deal - the United States, Israel and Saudi Arabia.
Iranian president Hassan Rouhani has warned the US will suffer "historic remorse" if Mr Trump pulls out of the deal.
Johnson wrote an opinion piece for The New York Times in which he acknowledged the 2015 agreement that gave Tehran sanctions relief in exchange for curbing its nuclear program has its disadvantages.
Perhaps it was just a coincidence that this obvious scam targeting my family had all the hallmarks of an intel op and coincided with Team Trump's reported efforts to "dig up dirt" on me. The natural gas pumped by the deal will go toward Iran's domestic market.
Netanyahu's accusations against Iran, as tend to be the case, were completely false. Tehran can install more centrifuges after 10 years, for example, and can resume research and development after eight years. We do not want confrontation, but if it should happen, it is better to now than later. But Radio Farda's correspondent in Dubai says that there is almost no trading of Iranian currency in the Emirates vibrant foreign currency market.
He added: "The wisest course would be to improve the handcuffs rather than break them".
Some of that could happen within days.
The operation to 'get dirt' on Barack Obama's former staffers Ben Rhodes and Colin Kahl was launched last May, according to unnamed sources and documents cited by UK newspaper The Observer.
Trump has voiced three main issues he has with the Iran deal. Gen. Amir Ali Hajizadeh; the head of its surface-to-surface missile program; Col. Mahmoud Bakri Katrem Abadi; and the head of its air defense operations, Ali Akhbar Tzeidoun.
The Iranian foreign minister Mohammad Zarif said on Monday that Tehran's "fierce reaction" will "not be pleasant for the US" if it abandons the nuclear deal. But judging from his harsh criticism, that seems unlikely. "The president is rightly concerned about Iran's regional activities, which are malign and damaging to security and stability". Those who work through the Central Bank, especially importers of Iranian oil, risk violating U.S. sanctions. Macron urged Trump not to withdraw when he met him in Washington late last month.
Q: What would Iran do? The exception is French oil giant Total SA, which in July signed a US$5 billion, 20-year agreement with Iran and a Chinese oil company to develop the country's massive South Pars offshore natural gas field.
