  The ATLAS Collaboration has reported excesses in the search for resonant
diboson production with decay modes to hadronic final states at a diboson
invariant mass around 2 TeV in boosted jets from $WZ$, $W^+W^-$, and $ZZ$
channels. Given potential contamination, we investigate the anomalies in
leptophobic $U(1)_{\rm LP}$ models. We show that leptophobic models can be
constructed in flipped $SU(5)\times U(1)_X$ models from free fermionic string
constructions and Pati-Salam models from D-brane constructions. Additionally,
we perform a collider phenomenological analysis to study production cross
sections for $pp \to Z' \to jj/t \bar{t}/WW/Zh$ and discover the excess can be
interpreted in both the leptophobic flipped $SU(5)\times U(1)_X$ models and
intersecting D-branes.
