What' s the different between who says or who said

the isnt much difference here but i would think that

'who says' is when someone has recently said it like in the presence

'who said' is like in the past

if you put it in context for example:

she says this is good for you

she said its good for you

its more or less the same meaning

hope this helps :)

who says = presence

who said= past tense
