The Cryogenic Underground Observatory for Rare Events (CUORE) is the first cryogenic experiment searching for neutrinoless double-beta () decay that has been able to reach the one-ton scale. The detector, located at the Laboratori Nazionali del Gran Sasso in Italy, consists of an array of 988 TeO crystals arranged in a compact cylindrical structure of 19 towers. Following the completion of the detector construction in August 2016, CUORE began its first physics data run in 2017 at a base temperature of about 10 mK. Following multiple optimization campaigns in 2018, CUORE is currently in stable operating mode. In 2019, CUORE released its 2\textsuperscript{nd} result of the search for with a TeO exposure of 372.5 kgyr and a median exclusion sensitivity to a Te decay half-life of yr. We find no evidence for decay and set a 90\% C.I. (credibility interval) Bayesian lower limit of yr on the Te decay half-life. In this work, we present the current status of CUORE's search for , as well as review the detector performance. Finally, we give an update of the CUORE background model and the measurement of the Te two neutrino double-beta () decay half-life.
