‘US Republican Senator Rand Paul is pushing for a vote on President Donald Trump’s recent $110 billion arms deal with Saudi Arabia, arguing that it would make Washington complicit in the Riyadh regime’s ongoing war crimes in Yemen.

Paul, who ran against Trump in last year’s presidential race, was expected to introduce the measure on Wednesday, according to his aide.

The Kentucky lawmaker is hoping for a vote in early June. The Arms Export Control Act allows Paul to bring up the measure in the Senate after 10 calendar days.

Trump signed the $110 billion deal during the first leg of his maiden overseas trip in Saudi Arabia over the weekend.

Reportedly brokered by the Republican president’s son-in-law Jared Kushner, the massive package includes American missiles, bombs, armored personnel carriers, Littoral Combat Ships, terminal high altitude area defense (THAAD) missile systems and munitions.’
