Discord.py program using 100% of a core

I have a Discord bot running in python on a Raspberry Pi 3B+. The purpose of this program is to send the lab status to our server by the push of a physical button. I've noticed that the program itself does not always want to cooperate and has been using 100% of a core at all times. I believe the hardware is still healthy and the only other thing that's running is the OS itself. htop reads that the individual program is using 98-101% of a core every time I check.

# Pull in server token and channel ID
with open('/home/pi/EVC-Discord-Bot/token.txt', 'r') as f:
    TOKEN = f.read()
with open('/home/pi/EVC-Discord-Bot/channel.txt', 'r') as f:
    CHANNEL = f.read()

# Define bot properties

bot = commands.Bot(command_prefix='!', description=description)

client = discord.Client()
