Protesters chanted "Lock him up" as President Trump returned to the White House on Sunday night, one week into their anti-Trump rally following a summit with Russian President Vladimir Putin.

Crowds have been gathering outside of the White House for seven days and greeted the president and first lady Melania Trump as they arrived from a weekend at Trump's Bedminster, N.J., golf course.

The ongoing protests are being organized by Adam Parkhomenko, a former adviser to Hillary Clinton.

The group began to "Occupy Lafayette Square" following Trump's controversial joint press conference with Putin last week in Helsinki.

The protesters have aimed to disrupt Trump's nightly routine and have brought in noisy bands, artists and musicians to keep the president awake at night.

Crowds have stood outside the White House gates, now dubbed the "Kremlin Annex," and watched an 18-person Mariachi band, opera singers and a hip-hop band with dancers perform.

Parkhomenko said drummers will be performing on Pennsylvania Avenue on both Monday and Tuesday nights.

A Russian translator will also be available on Tuesday to translate what the protesters are chanting "from English to Russian very loudly," he said on Twitter.

Several high-profile names stopped by to join the protests last week, including Rep. Joaquin Castro (D-Texas), actress and activist Alyssa Milano, and Stormy Daniels's attorney, Michael Avenatti.
