Activists were on Capitol Hill this week to urge support for Ukraine.
Insider attended a meeting between the activists and Sen. Markwayne Mullin, an Oklahoma Republican.
Mullin supports aid for Ukraine, but staff warned that calls from constituents have been "mixed."
A majority of Republican lawmakers are no longer so sure, at least publicly, that defending Kyiv from the Kremlin is in America's strategic interests.
Republican lawmakers are responding to concerns expressed by Republican voters — the people who will ultimately decide their political future.
