Ed Pilkington complains at the Guardian that legislation is being pushed in multiple states to prohibit the practice of Islamic religious law in US courts:

Anti-sharia legislation is spreading in state legislatures across the US, as Donald Trump’s hostile stance towards Muslims appears to be emboldening rightwing Islamaphobes.

In 2017 there were 23 new bills introduced in 18 states attempting to prohibit the practice of Islamic religious law, or sharia, in US courts. The rash of new bills brings the total number of such legislative efforts since 2010 to 217 in 43 states, according to the Haas Institute at UC Berkeley which monitors the anti-sharia movement.

…

Most of the recent bills are careful not to refer overtly to sharia or Islam, as to do so would be to expose the legislation to the scrutiny of federal courts on grounds of religious discrimination. Instead, they talk of “foreign laws” being banned in US jurisdictions.
