doubts

[dilodi83]

which is correct?

1) to cast doubt on something to someone: You're casting doubts on Michael's story to me.

2) to cast doubt to someone on something: You're casting doubts to me on Michael's story.

Neither sounds right to me. These work:

You're casting doubts on Michael's story to me.
You are making me doubt Michael's story.
You are giving me doubts about Michael's story.
