(CNSNews.com) -- House Rep. Tulsi Gabbard (D-Hawaii), an Iraq war veteran and contender for the Democratic presidential nomination, replied to President Donald Trump's tweet that America is "locked and loaded," ready to help Saudi Arabia, by stating that Trump is serving "his Saudi masters" and not putting "America First."
"Trump awaits instructions from his Saudi masters," tweeted Gabbard on Sept. 15. "Having our country act as Saudi Arabia's bitch is not 'America First.'"
On Saturday, bomb-laden drones attacked Saudi Aramco's Abqaiq oil processing facility in Baqyaq, Saudi Arabia. The damage has forced Saudi Arabia to cut its processing production by nearly 50 percent.
Although Houthi rebels fighting against the Saudis in Yemen initially took credit for the drone attacks, the United States has said that Iran appears to be behind the action.
“We call on all nations to publicly and unequivocally condemn Iran’s attacks," said Secretary of State Mike Pompeo on Twitter. "The United States will work with our partners and allies to ensure that energy markets remain well supplied and Iran is held accountable for its aggression."
Pompeo also tweeted, "Tehran is behind nearly 100 attacks on Saudi Arabia while Rouhani and Zarif pretend to engage in diplomacy. Amid all the calls for de-escalation, Iran has now launched an unprecedented attack on the world’s energy supply. There is no evidence the attacks came from Yemen."
On Sept. 15, President Trump tweeted, "Saudi Arabia oil supply was attacked. There is reason to believe that we know the culprit, are locked and loaded depending on verification, but are waiting to hear from the Kingdom as to who they believe was the cause of this attack, and under what terms we would proceed!"
