Ted Cruz Threatens To Filibuster Clean Debt Limit Hike

Sen. Ted Cruz (R-TX) will push a 60-vote threshold, meaning he’s threatening to filibuster, on a clean debt ceiling increase extension.
Cruz’s office confirmed the Texas senator’s plans to TPM on Tuesday afternoon.
Cruz’s move means lawmakers will need to rally 60 votes in the chamber to pass the bill, and Democrats only control 55 votes.
