Rick St. Hilaire has a detailed discussion supporting S.2212:
The proposed bill clarifies the spirit of a federal law in force for over 35 years, but weakened in the last few years. Congress in 1965 passed IFSA (formally known as the Immunity from Seizure Under Judicial Process of Cultural Objects Imported for Temporary Exhibition or Display). Lawmakers passed it because they wanted to promote the importation of art. They wanted to let foreign art lenders know with certainty that their cultural works would not become entangled in litigation once on American soil.
