How to include arbitrary HTML in RMarkdown document?

I'm using RMarkdown to author a blog via blogdown. I would like to include, for example, embedded tweets. Like below:

<blockquote class="twitter-tweet" data-partner="tweetdeck">
  <p lang="en" dir="ltr">Section 1.5 uses the gutenbergr package to pull literary text. Unfortunately, the function doesn&#39;t get through our work firewall.</p>&mdash; Jeremy GH (@JGreenbrookHeld) 
  <a href="https://twitter.com/JGreenbrookHeld/status/912774476533719040?ref_src=twsrc%5Etfw">September 26, 2017</a>
</blockquote>
<script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script>

I know how to include R code which will be evaluated, but I don't know how to just stick in a block of HTML code and have it passed along directly. Any tips?

As an example, I have a simple RMarkdown document

---
title: "Test"
author: "Mark Ewing"
date: "October 2, 2017"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## R Markdown

<blockquote class="twitter-tweet" data-partner="tweetdeck">
  <p lang="en" dir="ltr">Section 1.5 uses the gutenbergr package to pull literary text. Unfortunately, the function doesn&#39;t get through our work firewall.</p>&mdash; Jeremy GH (@JGreenbrookHeld) 
  <a href="https://twitter.com/JGreenbrookHeld/status/912774476533719040?ref_src=twsrc%5Etfw">September 26, 2017</a>
</blockquote>
<script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script>

When I just plop HTML down in the middle of the document I get this error:

pandoc.exe: Could not fetch //platform.twitter.com/widgets.js
//platform.twitter.com/widgets.js: openBinaryFile: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 67
In addition: Warning message:

If I wrap it first in the code marker ``` it blockquotes the html instead of rendering it.

Although one solution has been pointed in a comment above (add the protocol http:// to the URL of widget.js), I want to mention the blogdown documentation, where I specifically used embedding Tweets as an example. I don't recommend you to use the embed code provided by Twitter, but use a Hugo shortcode instead, which is much more lightweight (although it essentially generates the same thing under the hood).
