A bipartisan letter signed by nearly 400 US Congress members is calling on President Trump to remain militarily engaged within Syria, while claiming to be "deeply concerned" about extremists in the country. 

President Trump had announced a pullout from Syria in December, but had already disavowed it repeatedly by February. Still, lawmakers want to keep emphasizing how enthusiastic about the Syrian War they are, and push Trump into escalating it against various other parties. 

Once a war about ISIS, the letter urges Trump to "increase pressure on Iran and Russia with respect to their activities in Syria." The US already treated Syria as something of a proxy war, and the letter suggests they do away with all pretext and just make it into a war against Iran and Russia over Syria. 

The lead signers of the letter were top party leaders and ranking committee members in both the House and the Senate. This once again underscores that on matters of war, Democrats and Republicans within leadership positions are almost completely in-line on keeping the wars going.
