The Saudis are encouraged by Trump's hardline on Iran.
"The meeting today restored issues to their right path and form a big change in relations between both countries in political, military, security and economic issues," the senior advisor said in a statement.
The Saudis were further encouraged on April 19 when Secretary of State Rex Tillerson said the Trump administration was in the process of reviewing the lifting of sanctions against Iran. Tillerson denounced the country as a sponsor of terrorism.
"Everywhere you look, if there's trouble in the region, you find Iran," James "Mad Dog" Mattis, Trump's Secretary of Defense, told reporters. "Right now, what we're seeing is the nations in the region and others elsewhere trying to checkmate Iran, and the amount of disruption and the amount of instability they can cause."
