Why wont BeautifulSoup extract all the HTML from a public twitter page?

Question

I am trying to write some code to extract tweets from a public twitter page (Nike store) using the Python BS4 module. When I print the page HTML into the console, only some of the HTML is printed - when I try to search (ctrl +F) the specific class values for a tag from the console output and it returns with zero results. Why is this happening?

Here a code snippet:

from bs4 import BeautifulSoup as soup

from urllib.request import urlopen

import re

if __name__ == '__main__':

    # Read webpage into page_html' and close connection to webpage'
    first_page = 'https://twitter.com/nikestore'
    url_client = urlopen(first_page)
    page_html = url_client.read()
    url_client.close()
    print(page_html)
