House Speaker Nancy Pelosi announced that she joined forces with Sen. Lindsey Graham in a push to overturn President Trump’s “dangerous decision” on Syria.

The California Democrat announced on Monday that she and Graham agreed to “a bipartisan, bicameral joint resolution” on the president’s controversial decision to pull U.S. troops from northern Syria.

Pleased to have a conversation with Senator @LindseyGrahamSC this morning. Our first order of business was to agree that we must have a bipartisan, bicameral joint resolution to overturn the President’s dangerous decision in Syria immediately. — Nancy Pelosi (@SpeakerPelosi) October 14, 2019

Senior Republican lawmakers have criticized Trump’s decision and have been warning of the dangerous consequences of the vacuum that would be left behind as U.S. troops depart, as well as condemning the apparent abandonment of Kurdish allies who helped the U.S. defeat ISIS.

Graham confirmed the conversation with Pelosi, but only seemed to focus on the sanctions, saying he had spoken with the Democrat leader and they agreed also on the additional sanctions against Turkey which began its offensive into Syria soon after Trump’s announcement last week.

Just spoke with Speaker Pelosi regarding congressional action on Turkey’s incursion of Syria. Speaker supports bipartisan sanctions against Turkey’s outrages in Syria. She also believes we should show support for Kurdish allies and is concerned about the reemergence of ISIS. — Lindsey Graham (@LindseyGrahamSC) October 14, 2019

I will be working across party lines in a bicameral fashion to draft sanctions and move quickly, appreciating President Trump’s willingness to work with the Congress. The Speaker indicated to me that time was of the essence. — Lindsey Graham (@LindseyGrahamSC) October 14, 2019

Pelosi called for “a stronger sanctions package than what the White House is suggesting,” in additional tweets following her talks with the South Carolina Republican.

As we find ourselves in a situation where the President gave a green light to the Turks to bomb and effectively unleashed ISIS, we must have a stronger sanctions package than what the White House is suggesting. — Nancy Pelosi (@SpeakerPelosi) October 14, 2019

Though neither of the lawmakers revealed any details of proposed legislation, they were in agreement that sanctions were needed.

The president, who is scheduled to meet with Graham on Monday, had also indicated that he was considering “imposing powerful sanctions on Turkey” in a tweet on Sunday.

Dealing with @LindseyGrahamSC and many members of Congress, including Democrats, about imposing powerful Sanctions on Turkey. Treasury is ready to go, additional legislation may be sought. There is great consensus on this. Turkey has asked that it not be done. Stay tuned! — Donald J. Trump (@realDonaldTrump) October 13, 2019

On Monday, he again tweeted about “big sanctions” coming ,but noted that the “Never ending wars will end!”

“Do people really think we should go to war with NATO Member Turkey?” he asked.

….Kurds may be releasing some to get us involved. Easily recaptured by Turkey or European Nations from where many came, but they should move quickly. Big sanctions on Turkey coming! Do people really think we should go to war with NATO Member Turkey? Never ending wars will end! — Donald J. Trump (@realDonaldTrump) October 14, 2019

On Sunday, Graham had indicated that Trump’s cooperation with Congress to stop Turkey’s aggression in Syria would be “a game changer.”

“I applaud his decision to work with Congress to stop Turkeys [sic] aggression in Syria through crippling economic sanctions,” he tweeted. “This decision by President Trump will be a game changer — in all the wrong ways — for Turkey.”
