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.

During his secretary of state confirmation hearing, Sen. Marco Rubio, R-Fla., said there "will have to be concessions made" by both Russia and Ukraine to end the ongoing conflict between the countries.
