TypeError: todo.filter is not a function React Js

I'm creating a todo app and I ran across a issue im confused on how to fix. I get a TypeError: todo.filter is not a function when I click on the Icon button to remove to todo task. this is what I have in my code.

import React from 'react'
import Button from '@material-ui/core/Button';
import DeleteIcon from '@material-ui/icons/Delete';

function Todo({todo, setTodo}) {

    const removeHandler=()=>{

        setTodo(todo.filter((el) => el.id !== el.id))
        console.log(todo)
    }


    return (
        <>     
        <div className="list-container"> 
         <li className="todo-item" key={todo.id}>{todo.text}</li>

        <Button variant="contained" color="secondary" size="small">
        <DeleteIcon onClick={removeHandler}/>
        </Button>
        </div>
        </>


    )
}

export default Todo
