The article quotes the Jerusalem Post:
Maariv reported that former US secretary of state John Kerry met in London with a close associate of PA President Mahmoud Abbas, Hussein Agha, for a long and open conversation about a variety of topics. Agha apparently reported details of the conversation to senior PA officials in Ramallah. A senior PA official confirmed to Maariv that the meeting took place.
During the conversation, according to the report, Kerry asked Agha to convey a message to Abbas and ask him to “hold on and be strong.” Tell him, he told Agha, “that he should stay strong in his spirit and play for time, that he will not break and will not yield to President [Donald] Trump’s demands.”
…According to Kerry, Trump will not remain in office for a long time. It was reported that Kerry said that within a year there was a good chance that Trump would not be in the White House.
…He surprised his interlocutor by saying he was seriously considering running for president in 2020. When asked about his advanced age, he said he was not much older than Trump and would not have an age problem.
…In a report on the conversation, Agha said that Kerry appears to be “crazy about things,” very energetic, and someone who is yearning to help realize the dream of peace between Israelis and Palestinians.
As a country we have not enforced the Logan Act; however, this does seem a bit over the top.
Wikipedia definesThe Logan Act as follows:
“The Logan Act is a United States federal law that forbids unauthorized citizens from negotiating with foreign governments. It was passed in 1799 and last amended in 1994. Violation of the Logan Act is a felony, punishable under federal law with imprisonment of up to three years.”
