Can I safely add a third wire to my TV outlet that is already running behind the TV setup?

I’m in the process of running a wire behind my TV. Do you think it’s safe to connect a third wire to this outlet? Or should I avoid it?
Connect them with wire nuts inside the box and then run a wire from the connections to the new outlet.

It’s actually called pig tailing – you need to connect each color together (black to black, white to white, ground to ground) and then add a 6″ piece (the pig tail) to each. In total, you’ll have 4 connections. Secure them with marrettes, then connect each of the pigtails to the appropriate screw. And you’re all set.
Sorry I forgot to mention it was called pig tailing, I was just trying to simplify things.
Everything’s fine, I’m just here trying to assist like you.
Connect the wires together and attach 6-inch wires to the outlet. This will give you 4 black wires, 4 white wires, and 4 ground wires.
As others have mentioned, make a pigtail for it. One additional tip is to hold the wire nut with one hand and tug on each wire individually to ensure they are all securely connected. If any wires feel loose, redo the connection. Also, be sure to strip the insulation adequately for a good connection without exposing too much wire beyond the nut.
If the box is metal, remember to screw the ground wire into the box and create a pigtail for the ground wires. If the new outlet is plastic, the ground does not need to be attached to the box. Lastly, ensure the wire gauge matches the existing wire it is connecting to.
Mentioned that these could always be used because depending on the size of the box, adding the wire nut might be tight inside the box.
I believe you meant to say that if the box is plastic, right ? It appears to be made of plastic.
Hey , I didn’t notice that in the picture. Plastic doesn’t need to be grounded, right?
Sure, you’re able to connect a wire from this outlet to the one located behind your television. Focus solely on powering your TV with this setup. If you plug in additional electronics to the outlet behind your TV and trip the circuit breaker, it means you’re exceeding the amperage limit.
Hahaha it’s impossible to determine the amps on that circuit from this picture.
Here’s a question that might make you rethink your approach. Is the top or bottom of the outlet connected to a switch?
Ted suggested it’s a good idea to ask, but the tie tab on the hot side is still intact.
Pointed out that, but maybe I was not seeing it correctly. I have made that error in the past.
Just twist the wires together.
Ponytails are more reliable for making a connection than screws on the outlet.

Simply insert it into the ports located at the back of the outlet.
No offense, but stabs are known for failing. I’ve repaired numerous outlets for people because the stab connections have loosened. Personally, I steer clear of stabs.
If your socket overheats, you risk losing all power downstream on that circuit. Using a pigtail can help avoid this.
Avoid doing a half-hearted job just to save a few bucks by attempting a DIY. I get the urge to take shortcuts, but in the long run, it’s not worth it. Install proper pigtails and invest in new matching receptacles when purchasing wire nuts or wagos. Do it correctly from the start and you won’t have to think about it again.
Just pigtail it. Use 14 gauge wire specifically designed for the job, don’t take shortcuts.
