This is Psalm 140, edited by me for this purpose. (It’s true that “politics” hasn’t changed much in 3,000 years!)
Deliver President Trump, O LORD, from evil men; preserve him from violent men, who plan evil things in their hearts and stir up confrontation continually. They make their tongue sharp as a serpent’s, and under their lips is the venom of asps. Guard him, O LORD, from the hands of the wicked; preserve him from violent men, who have planned to trip up his feet. The arrogant have hidden a trap for him, and with cords they have spread a net; beside the way they have set snares for him. I say to the LORD, You are my God; give ear to the voice of my pleas for mercy, O LORD! O LORD, my Lord, you are the strength of our salvation, cover our heads in the day of battle. Grant not, O LORD, the desires of the wicked; do not further their evil plot, or they will be exalted! As for the head of those who surround surround the president, let the mischief of their lips overwhelm them! If they don’t accept your grace, Let burning coals fall upon them! Let them be cast into fire, into miry pits, no more to rise! Let not the slanderer be established in the land; let evil hunt down the violent man speedily! I know that the LORD will maintain the cause of the afflicted, and will execute justice for the needy. Surely the righteous shall give thanks to your name; the upright shall dwell in your presence.
