Bash Save Multiline Git Log Output to Environment Variable

I'm trying to save the output of a git command to an environment variable in a GitHub Actions step and it's grabbing the first line of the output and leaving off the rest. The container this is running on is ubuntu-latest.

Here's how I'm trying to capture it:

TMP_CHANGES=`git log origin/master..`

What I expect from echo $TMP_CHANGES:

What I get:

commit f179fb811618cc5a2f07637a2ecb394a43ebee21

What am I missing? How can I capture and save the full multiline output to the variable while preserving multiline formatting?
