Corker, the Republican chairman of the Senate Foreign Relations Committee, acknowledged the case - if Saudi responsibility is confirmed - could complicate the US strategy to contain Iran, in its bid to gain influence throughout the Middle East.
The letter demands that the White House "determine whether a foreign person is responsible for the extrajudicial killing, torture or gross violation of internationally recognized human rights". He must then report to the Senate within 120 days with a determination and a decision on the imposition of sanctions. Saudi officials haven't acknowledged that.
Decades of close U.S. -Saudi relations, which have only intensified under Trump, appeared in jeopardy by the suggestion of a carefully plotted murder of a government critic, Jamal Khashoggi, 59, who disappeared a week ago after entering a Saudi consulate in Turkey.
In response, an official source at the Saudi consulate denied that Khashoggi was killed inside the consulate and denounced what he described as "baseless accusations".
Former U.S. Energy Secretary Ernest Moniz said he has suspended his role on the board of Saudi Arabia's planned mega city NEOM until more is known about Khashoggi.
According to some friends of Khashoggi, over the past four months, senior Saudi officials close to bin Salman had called Khashoggi to offer him protection and even a high-level job working for the government if he returned to his home country.
"At this time, I implore President Trump and First Lady Melania Trump to help shed light on Jamal's disappearance", she said. "We do not like seeing what's going on". Frankly, because it's a reporter, you could say in many respects, it brings it to a level. "Violence against journalists should be condemned, but at this point, we don't know what happened". "We can not let this happen, to reporters, to anyone". Is it possible that camera systems didn't exist at the Saudi Arabia Consulate, where the incident took place? The Trump administration's Middle East policy, ranging from issues of Iran, Syria and Israel, has been built around the Saudi alliance despite criticism of the kingdom's abysmal human rights record and the war in Yemen.
CCTV via Hurriyet / Associated Press This image from CCTV video obtained by the Turkish newspaper Hurriyet reportedly shows Saudi journalist Jamal Khashoggientering the Saudi consulate in Istanbul on October 2, 2018.
Mr Khashoggi, a United States resident and critic of the Saudi monarchy, entered the Saudi consulate in Istanbul on 2 October and has not been seen since.
What else does the video show?
Corker described his talks with Khalid bin Salman, the Saudi ambassador to the U.S., as "not a great conversation", and asked to show him video footage of him leaving the consulate.
According to pro-government daily Sabah, the team arrived in Istanbul on two private planes, one which landed after 03:00 am (0000 GMT) on Tuesday while the second plane landed around 05:00 pm (1400 GMT) after Khashoggi entered the consulate.
Embassies and consulates under the Vienna Convention are technically foreign soil and must be protected by host nations.
Scarborough stressed that when Trump visited Saudi Arabia past year, the Saudi government "made such a fool of him".
Oil prices steady after Iranian exports fall further
The Turkish president, Recep Tayyip Erdoğan, has promised a transparent investigation into Khashoggi's fate. He said he'll try to force a vote in the Senate this week blocking USA arms sales to Saudi Arabia.
Sevastova stuns Osaka to reach China Open final
I think after the second match I started feeling like I was hitting the ball well and I could see the ball really well. Wozniacki was in solid form throughout the tournament and did not drop a single set to romp towards the title.
