Republicans Move to Impeach Mayorkas Over Immigration Policies
• Republicans push ahead with articles of impeachment against Homeland Security Secretary Alejandro Mayorkas, accuse him of violating immigration laws
• Effort extremely unlikely to succeed given Democratic control of Senate, but fuels arguments against GOP's seriousness on immigration issues
• Articles allege Mayorkas failing to detain migrants seeking asylum, but administrations have struggled with capacity for humane detention facilities
• Former President Trump pressures Senate Republicans to kill bipartisan negotiations on border security legislation
• Biden impeachment also faces challenges, with swing district Republicans showing little overt support and very slim GOP House majority
