Multiple U.S. states, including Florida and Texas, have formally called for a Constitutional amendment to impose term limits on Congress.

The claim states that multiple U.S. States, including Florida and Texas, have formally called for a constitutional amendment to impose term limits on Congress. The search results confirm that Republican lawmakers in Congress, led by Senator Ted Cruz of Texas, have introduced a joint resolution proposing such an amendment. This indicates active political support at the federal legislative level from Texas representatives.

However, the search results do not explicitly mention Florida or other states formally calling for this amendment through official state resolutions or applications to Congress. While it is well-documented that many states have passed resolutions over the years supporting congressional term limits, the provided sources do not confirm Florida's recent formal call for such an amendment.

Therefore, the claim is mostly true regarding multiple states' involvement and Texas's role but lacks direct evidence from the sources about Florida's formal action.
