[Python] Match 2 strings then print both matches

I have 2 lists that i want to match and then print the matched values from both list A and list B

import re

A="""
ABB1265 DUE blah blah
ADD809 DUE blah blah
blah ADD blah
TIME 20:33 ADD223 blah blah.
"""

B = """
GFA
ADD
ABB
TI
"""



pattern = re.compile("(" + "|".join(i.strip() for i in B.strip().splitlines()) + ")")
for line in A.splitlines():
line = line.strip()
m = pattern.match(line) #Using re.match
if m:
print(line,end=",")
print(m.group(1))


This code is matching only words at the start of the line and it also taking strings inside strings

the output currently is this:

ABB1265 DUE blah blah,ABB
ADD809 DUE blah blah,ADD
TIME 20:33 ADD223 blah blah.,TI


My ideal output is this:

ABB1265 DUE blah blah,ABB
ADD809 DUE blah blah,ADD
blah ADD blah,ADD
TIME 20:33 ADD223 blah blah.,ADD
