We revisit D-term inflation with the bounds of the cosmic string tension from gravitational wave observations and consider the possible deviation of the spectral index compared with $\Lambda$CDM model in light of pre-recombination resolutions of the Hubble tension. D-term inflation requires very small coupling constants under these constraints. We show that large coupling constants can be achieved in the case of D-term inflation on the brane.
