Bring is an irregluar verb, that is, a verb that has its own particular conjugations rather than following the same pattern followed by other verbs. That irregular pattern might not seem logical to us, or we might not like the pattern; nevertheless, it’s the correct pattern.
Despite how many times I’ve heard brang and brung uttered, there is no brang or brung in the conjugation of bring. The correct pattern is bring, brought, has/have brought.
I bring my portfolio to every job interview.
She brought the baby home in a white blanket (not She brang the baby home).
He has brought enough donuts for the entire department (not He has brung enough donuts).
