Russia’s nearly three-year invasion of Ukraine has become a “war of attrition” and a “stalemate” that must be ended, Senator Marco Rubio, President-elect Donald Trump’s pick to be secretary of state, told senators at his confirmation hearing on Wednesday.

Sen. Marco Rubio used his confirmation hearing Wednesday to warn a Senate panel that China might move against Taiwan before the decade is over and that a potential ceasefire agreement between Russia and Ukraine must provide the Ukrainians with sufficient leverage to deter a repeat invasion in the future.
