Red line emerges for House GOP as Trump continues Iran military operation

House Republicans are signaling they are largely OK with handing the reins to President Donald Trump as the United States and Israel continue their joint operations against Iran.

But there is a red line on the horizon for most GOP lawmakers; This will put dozens of lawmakers in a difficult position between supporting their party leaders and complying with Congress’s constitutional authorities.

R-Ga. “I would like to see congressional approval for boots on the ground,” Rep. Rich McCormick told Fox News Digital. But he added: “Right now it’s just an intervention, which is very similar to what Obama, Clinton and other presidents have done in my lifetime.”

The ongoing attacks, which have killed Iran’s supreme leader and other members of the upper echelons of Tehran’s repressive regime, have so far consisted of coordinated missile launches against military targets.

But the Trump administration has not ruled out a U.S. presence on the ground there, despite assurances that the mission would be limited and last only a few weeks rather than months or years.

“The president is doing what he has to do… I agree with the politics,” Rep. Chip Roy, R-Texas, told Fox News Digital. “If at some point this goes beyond that in terms of work on the ground and budget need and scope, if that starts to require our involvement, then we’ll look at that.”

Rep. Nancy Mace, R-S.C., said she also supports the operation, but added: “If ground troops were to get involved. I think that would be a very different discussion. We’re not at that point today.”

“We’re just trying to see how things progress every day at this point, but it would certainly be something that we as Congress would want to engage in discussion about,” Rep. Ryan Mackenzie, R-Pa., told Fox News Digital.

However, he also argued that forcing the operation to end too early could do more harm than good.

“Once the president takes that action, that first action, if we were to withdraw, he would actually leave all of his capabilities in place, leaving us more vulnerable and less safe, but we would be setting off such a conflict,” Mackenzie said.

“So we need to follow the targets, but we also need to be very careful to make sure they don’t go beyond what we can achieve.”

Rep. Mark Alford, R-Mo. Others, such as, were doubtful that the incident would come to this point.

“I don’t think we’ll get to this point. This is very different from Iraq or Afghanistan. The capabilities that we developed, the intelligence that we developed, working with the IDF, we had capabilities that we no longer have,” Alford told Fox News Digital.

“Now, when it comes to getting a foot on the ground, which I don’t think it will, that’s a whole different story… We’re only five days away from this, and I think what you’ve seen so far has had a tremendous impact.”
