Amid worldwide concern about the killing of Saudi journalist Jamal Khashoggi, some 200 protesters gathered in central Tunis on Monday night to protest the prince's Tuesday arrival for talks with the Tunisian president.
"MBS contributed to murdering somebody overseas and it is not strength to sort of mumble past that", Sasse told "Fox News Sunday", referring to the crown prince.
The visit is the fourth stop on the Crown Prince's tour of Arab nations which has so far taken in Bahrain, the UAE and Egypt.
Sen. Ben Sasse (R-Neb.), a vocal critic of the president, blasted the bombshell statement Trump issued last week in defense of Saudi Arabia, calling it "very weak".
Argentinian charges regarding war crimes-or even MbS's decision to back out of the G20 summit as potential charges loom-could send a strong message that the crown prince will be held accountable for his actions, even as Trump refuses to cut off support for him in the interest of the pair's business relationship.
Despite the worldwide outrage sparked by Khashoggi's killing, the crown prince has been emboldened in recent days by Trump's vocal support for him. We don't know, but it would be irresponsible not to find out, " Representative Adam Schiff of California, the ranking Democrat and expected new chairman of the House Intelligence Committee, said on "State of the Union, " accusing Trump of being "dishonest" about the crown prince's involvement".
"Tunisian civil-society groups are organizing protests against bin Salman's scheduled visit on Tuesday", Sakina Abdel Samad, a member of the Tunisian Journalists' Syndicate, told reporters on Monday at the syndicate's Tunis headquarters.
On Tuesday, hundreds more demonstrators carried placards reading: "No to polluting revolutionary Tunisia" and: "The murderer is not welcome", in marches organised by youth and women's rights groups.
The Saudi-led war has also taken a heavy toll on the country's infrastructure, destroying hospitals, schools, and factories.
Tunisian officials stressed the "historical and fraternal" relations between Tunis and Riyadh, adding that the region would suffer if Saudi Arabia, a regional power, was destabilised by Prince Mohammed's removal.
