cant solve remove_all_before task

so here is my code
from typing import Iterable

def remove_all_before(items: list, border: int) -> Iterable:
    it = []
    if items == []:
        return items
    for i in items:
        if border not in items :
            return items
        if items.index(border)<=items.index(i):
            it.append(i)
    return it
if __name__ == '__main__':
    print("Example:")
    print(list(remove_all_before([1, 2, 3, 4, 5], 3)))

    # These "asserts" are used for self-checking and not for an auto-testing
    assert list(remove_all_before([1, 2, 3, 4, 5], 3)) == [3, 4, 5]
    assert list(remove_all_before([1, 1, 2, 2, 3, 3], 2)) == [2, 2, 3, 3]
    assert list(remove_all_before([1, 1, 2, 4, 2, 3, 4], 2)) == [2, 4, 2, 3, 4]
    assert list(remove_all_before([1, 1, 5, 6, 7], 2)) == [1, 1, 5, 6, 7]
    assert list(remove_all_before([], 0)) == []
    assert list(remove_all_before([7, 7, 7, 7, 7, 7, 7, 7, 7], 7)) == [7, 7, 7, 7, 7, 7, 7, 7, 7]
