"TypeError: 'str' object is not callable" passing locator within expected_conditions through Python + Selenium

I'm receiving the following error:

Traceback (most recent call last): File "[redacted]", line 69, in wait.until(EC.element_to_be_clickable(By.ID("RptViewer_ctl09_ctl04_ctl00_ButtonLink"))) TypeError: 'str' object is not callable

Here's the section of code I believe is causing the problem:

66   browser.find_element_by_id('RptViewer_ctl09_ctl04_ctl00_ButtonLink')
67   drp = browser.find_element_by_id('RptViewer_ctl09_ctl04_ctl00_ButtonLink')
68   wait = WebDriverWait(browser, 10)
69   wait.until(EC.element_to_be_clickable(By.ID('RptViewer_ctl09_ctl04_ctl00_ButtonLink')))
70   drp.click()

I think what's causing the issue is the "ID('RptViewer_ctl09_ctl04_ctl00_ButtonLink')" section but I'm not sure if that's true and I'm not sure of how to fix it. Any guidance is extremely appreciated.

Thanks!
