Microsoft Corp. has shifted its legal representation in a lawsuit concerning its $69 billion acquisition of Activision Blizzard, replacing Simpson Thacher & Bartlett with Jenner & Block. This change follows Simpson Thacher's agreement to provide $125 million in pro bono legal services to causes favored by the Trump administration, prompted by a Trump executive order calling for pro bono help for law enforcement officers. The switch to Jenner & Block, which is actively challenging the Trump administration's executive orders in court, highlights the targeting of BigLaw firms by the administration. Jenner & Block has been vocal in its opposition to what it describes as an 'unconstitutional abuse of power' by the administration, particularly in relation to orders affecting their security clearances and federal contracts. Microsoft's decision to change firms reflects a preference for those that resist rather than comply with the administration's demands, amidst ongoing legal and corporate sector debates about responding to governmental pressures.
