We have carried out an observational campaign with the Swift satellite to observe with the UVOT and the XRT telescopes the field of view of 21 bright NVSS sources within the positional uncertainty region of the 3CR sources. Furthermore, we have searched in the recent AllWISE Source Catalogue for infrared sources matching the position of these NVSS sources. We have detected significant emission in the soft X-ray ban","authors_text":"A. Maselli (INAF-IASF-PA), A. Paggi (SAO). E. Liuzzo (INAF-IRA), C. P. O'Dea (Univ. of Manitoba, D. E. Harris (SAO), F.
