A petition calling for charges against Republican senators who sent a letter to Iran's leaders has collected more than 187,000 signatures in two days.While the US is attempting to reach an agreement with Iran government, "47 senators saw fit to instead issue a condescending letter to the Iranian government stating that any agreement brokered by our president would not be upheld once the president leaves office," according to the petition.
It further claims that the senators "committed a treasonous offence when they decided to violate the Logan Act, a 1799 law which forbids unauthorized citizens from negotiating with foreign governments."
Violation of the Logan Act is a felony, and punishable with imprisonment of up to three years, according to federal law.
A deadline was set for April 8 to collect 100,000 signatures in order to get a response from the White House but organizers have already almost doubled the goal.
The senators sent the letter to Iran on Monday and said any nuclear deal between the US administration, along with world powers, and Tehran, could be reversed and that President Barack Obama will leave office in January 2017, but the Senators will stay in office "well beyond then, perhaps decades."
According to the Constitution, the president is responsible for international negotiations and finding agreements with foreign leaders and countries.
Congress, however, has to ratify any agreement.
