Constitutional Attorney Robert Barnes says "Yes."

"Subsection 4 of the 14th Amendment provides: “The validity of the public debt of the United States, authorized by law…shall not be questioned.” This imposes three elements: first, it concerns “public debt”; second, that public debt must be “authorized by law”; and third, the only limitation is that it “not be questioned.” Of note, section 5 only gives one branch “power to enforce” this – Congress “by appropriate legislation.” At the outset, there is an argument that no role exists for any branch of government but Congress, as Congress alone is given the power to enforce. However, unsurprisingly, both the executive and judicial branch reject this limit on their own power, and claim the right to enforce it themselves, treating the provision as simply an authorization of legislation, and not a restriction on the other branches of government. As the historical context makes clear, this Amendment focused on future Confederates joining Congress and revoking the debt issued during the Civil War, or trying to require Union repayments of Confederate debt. The application of this provision to current times shows the expansive effect of its plain language."
