Good morning.

A backlash is growing against Saudi Arabia in Congress after an influential Democratic senator threatened to freeze weapons sales and security cooperation with the kingdom after its decision to support Russia over the interests of the US.

Frustration with Saudi Arabia is escalating on Capitol Hill. Chris Murphy, another Democratic senator, last week called for a wholesale re-evaluation of the US alliance with Saudi Arabia" and Tom Malinowski, a Democratic congressman, introduced legislation to withdraw US troops from the kingdom and the United Arab Emirates.
