Conflate

To combine two or more distinct things into one, often mistakenly or confusingly

Latin conflare, 'to blow together, fuse' (con-, 'together' + flare, 'to blow')

"Reporting that names only one limb of the Opposition's two-part demand conflates two distinct standoffs into a single grievance, losing the fact that the House had already forced one ministerial resignation before pressing a second demand."
