Recently, Kundu et al (2019) reported that the globular cluster NGC 5024(M53) possesses five extra-tidal RR Lyrae. In fact, four of them were insteadknown members of a nearby globular cluster NGC 5053. The status of theremaining extra-tidal RR Lyrae is controversial depending on the adopted tidalradius of NGC 5024. We have also searched for additional extra-tidal RR Lyraewithin an area of $\sim8$~deg$^2$ covering both globular clusters. Thisincludes other known RR Lyrae within the search area, as well as stars thatfall within the expected range of magnitudes and colors for RR Lyrae (and yetoutside the cutoff of 2/3 of the tidal radii of each globular clusters forsomething to be called "extra-tidal") if they were extra-tidal RR Lyraecandidates for NGC 5024 or NGC 5053. Based on the the proper motion informationand their locations on the color-magnitude diagram, none of the known RR Lyraebelong to the extra-tidal RR Lyrae of either globular clusters. In the caseswhere the stars satisfied the magnitude and color ranges of RR Lyrae, analysisof time series data taken from the Zwicky Transient Facility do not revealperiodicities, suggesting that none of these stars are RR Lyrae. We concludethat there are no extra-tidal RR Lyrae associated with either NGC 5024 or NGC5053 located within our search area.
