Speaking of the Congregation in her Prayers...

...perhaps the petitions for the government that appear in the Prayers of the Church would be good for us to use as tempers flare in DC:

Behold all who are in authority over us.  Supply them with Your blessing that they may be inclined to Your will and walk according to Your commandments.  (General Intercession)

Grant heath and prosperity to all who are in authority, especially to the president and congress of the United States, the governor and legislature of this state/commonwealth, and to all who make, administer, and judge our laws.  Grant them grace to rule according to Your good pleasure for the maintenance of righteousness and the hindrance and punishment of wickedness, that we may lead quiet and peaceable lives in all godliness and honesty. (General Prayer 1)

Bestow Your grace on all nations of the earth.  Bless especially our country, its inhabitants and all who are in authority.  Let Your glory dwell in our land that mercy and truth, righteousness and peace may abound in all places.  (General Prayer 2)

Preserve our nation in justice and honor that we may lead a peaceable life with integrity.  Grant health and favor to all who bear office in our land, especially the President and Congress of the United States, the governor and legislature of this state/commonwealth, and to all who make, administer, and judge our laws.  Help them to serve this people according to Your holy will.  (Prayer of the Church - Responsive)

For the government and all who have been set into positions of leadership that they may use the authority entrusted to them honorably and for the good of the people, let us pray to the Lord:  Lord, have mercy.  (Prayer of the Church - Ektene)

For the president, for all public servants, for the government and those who protect us, that they may be upheld and strengthened in every good deed, let us pray to the Lord:  Lord, have mercy.  (Evening Prayer)

For this nation, for our cities and communities, and for the common welfare of us all, let us pray to the Lord:  Lord, have mercy.  (Prayer and Preaching)

O merciful Father in heaven, because You hold in Your hand all the might of man and because You have ordained, for the punishment of evildoers and for the praise of those who do well, all the powers that exist in all the nations of the world, we humbly pray You graciously to regard Your servants, the President of the United States, the Congress of the United States; our Governor; and all who make, administer, and judge our laws, that all who receive the swords as Your ministers may bear it according to Your Word; through Jesus Christ, our Lord. Amen. (Bidding Prayer)
