The Guardian reports:

A libertarian group that has been funded by Leonard Leo and Charles Koch has mounted a legal challenge against Donald Trump’s tariff regime, in a sign of spreading rightwing opposition to a policy that has sent international markets plummeting.

The New Civil Liberties Alliance filed a suit against Trump’s imposition of import tariffs on exports from China, arguing that doing so under the International Emergency Economic Powers Act (IEEPA) – which the president has invoked to justify the duties on nearly all countries – is unlawful.

The group’s actions echo support given by four Republican senators last week for a Democratic amendment calling for the reversal of 25% tariffs imposed on Canada.

Last Wednesday’s amendment passed with the support of Mitch McConnell, the former Republican Senate majority leader, and his fellow GOP members Rand Paul, Susan Collins and Lisa Murkowski, who argued that tariffs on Canada would be economically harmful.

The action from the alliance has the potential to be even more emblematic, given its past backing from Koch, a billionaire industrialist, and Leo, a wealthy legal activist who advised Trump on the nomination of three conservative supreme court justices during his first presidency, which has given the court a 6-3 rightwing majority. The group received money from organisations affiliated with Leo and Koch in 2022. A spokesperson for Stand Together, a group partially funded by Koch and that has supported the alliance, said it was not involved in the legal case. [Continue reading…]
